1199 drops onto one cylinder

So having changed the coil and not being able to easily get my hands on a set of spark plug leads (really, they need to order them in from Italy!), replaced the MAP sensor. Got out for another ride and after 90 minutes and 60 miles it appears to be OK now. Who'd have thought a failed MAP sensor would have you stranded on the side of the road!
Was the map sensor available in the US and didn't need to be ordered? My current 899 has a high idle issue every so often and was thinking about replacing the MAP sensors.
 
So given my local shops can't get the bike in for a few weeks, I thought I'd try the coil option. Ordered a new one in and fitted it. Bike started fine, no engine warning light, so went out for a ride. Stayed close to home doing short legs out and back, where I could open it up a bit though. Appeared to be running smoothly, but after 30 minutes did it again, dropping the rear cylinder. Wait to the next morning and engine warning light is out and bike will start, but now running a bit rough. Cant get the MelcoDiag to work despite trying a few different things, but if the engine warning light is clearing would it even have a fault code to look for??
Regarding the trouble codes... yes, even if the dash pad isn't currently displaying an error, the errors were captured and can be read (and cleared) with MelcoDiag.

I bought mine on eBay cheap, identical to OEM

Yes, Colemans in Falls Church, VA had one in stock. Looks like aftermarket ones readily available too. Could try one of those first to see if it helps your situation.
 
i tested yet a Delphi(clone) 09359409 MAP Sensor.
has nothing to do with Duc and is in fact from china, even it is labeled made in USA.

atmospheric pressure at the moment is around 1024hPa. real vcc is 4.99 volts.
my measurements are not very exact, but enough to show that the original and clone differs.
just for information, maybe not important.
