Dangerous 2021 Ducati V2 Shutting down!

I have a 2021 Ducati Panagale V2 with 1899 miles on it. It seems that once the bike engine temperature gets to 180+ degrees the bike will just shut off. No idea as to why this is happening. I has happened to me 3 times already mostly when at a stop light (Luckily!) but it is becoming unsafe to drive.
I changed the coolant with Engine Ice a few weeks ago and checked the levels and they are fine so doesn't seem to be overheating
any help with this issue would be appreciated

Does it start back up immediately?

yes I can restart it after it shuts down

Tune?

Sure you bled the coolant completely?

yes opened the bleed valve and let it pour out flushed some distilled water thru it and then refilled with Engine Ice

You're sure you don't have a sensor failure? Does it really get hot? If it stops then restarts with a key off then goes for a while then shuts off again then starts after a key off.... Then it's a computer thing. Buffer fills up engine turns off. The key off clears one of the stored codes so then the bike will start again.

You have to stop making stuff up.

Does it run rough or exhibit any other symptoms? How hot was it (air temp) when it happened? I presume there's no check engine light, do you have the means to check the bike for a stored fault code?

Did you change the ECU mapping by any chance? ;-)

This is exactly what they do when you have an uncorrected repetitive fault. Mr Duessen is asking the same thing is the ECU corrupted. When the motor warms up it switches to normal operation so it seems as it does this it's seeing a fault. At that point the O2 sensors are coming online. Could be related to the oxygen sensors if they're trying to operate outside of their normal range (or an O2 sensor heater circuit failed) they fault. The problem is no codes? Weird. Buffer fills motor turns off. Then a key off will clear one stored fault and you get a restart. All for now I need to concentrate on making more stuff up.

I've had this happen on several motorcycles. Always when the engine is below operating temperature and when rolling off the gas.

In no way did Duessen's post affirm your buffer nonsense. I don't doubt the bike shutting off is potentially a fueling issue, but you started with this buffer .... when you made its existence up, "BBS buffer" to be exact, in another thread. Engine not starting (Fault code analysis)

God you do make me laugh. Make friends with a software guy, take a class, read up on how control software actually works, something. Here's an idea. Figure out where the connector is for the front O2 sensor (left near the bottom of case). Warm the bike up. Disconnect the oxygen sensor and see what it does. Why I understand this is because when I put arrows on my bike I turned off the oxygen sensors so I could map. When I traveled I realized that one cylinder had poor altitude compensation and above 9000 feet I had a lean surge. So when I got home I went in and turned the oxygen sensors back on because fixing it was a winter thing. But my OBD meter was on the fritz so I couldn't reset the O2 adaptives. So I went for a ride anyway and as the computer switched from the warm up cycle (no O2 sensor control) to O2 sensor control I saw a string of codes flash and then the motor turned off (really regulatory guys who thot this was a good idea try a limp mode) So I keyed off and it restarted, then it quit again. This time I keyed off multiple times and made it home. I went in and the multiple code recorded was O2 sensor out of range. This is because I didn't reset the adaptives. But what do I know.

I think your bike runs in spite of what you do to it.

My life has been about learning stuff. If one's does various things then one learns different and various things. And sometimes one can use things that one has learned about something else that one can transfer to the technology at hand to allow one to understand said technology. I was in the valley when Hughes started. I was working at the IBM plant at Ford and Cottle Roads. The 4 bits went initially into primarily scientific instruments, when the eight bits showed up the valley began to grow in earnest. So I've seen a lot of computer controlled applications across various tech platforms. Remember we used to do real manufacturing in the valley. My last job before my f**k you fund achieved sufficient size was telling a bunch of smart guys how we were going to turn start up cleanroom hand assembly into robotic assembly as the company grew. Please go take a software class.

I'd rather you wax poetic about the "BBS buffer."

The reason I think the the BBS has a buffer is that after I loaded about the third map and started the bike I threw an CEL and a second warning light was also. I went to look at the ECU and no codes. So I looked at the other computers. The BBS was stuffed with communication errors from loading the maps to the ECU. So I'm assuming that since it turned on the second warning light the BBS was telling me it was losing it's sense of humour. Or wait for it...., the buffer was close to full.

Or, you’re suppose to remove the BBS fuse when flashing.

no tune
yes I have removed the old coolant since it was over 2 years old let it drain out flushed with distilled water and refilled with Engine ICE

no key off just shuts off then have to use starter to restart don't have to shut off with key kinda like stalls out but no sputtering or anything when it does just shuts off

not that I am aware of a sensor failure no CEL on display
