Yikes it left u stranded.
I’m not gonna be able to help u other than the following link, but I’m curious how many miles and what year ur beautiful 1299 is?
AAA is the best, new battery/ year if yours fails. Plus the towing, can’t beat it. I have roadside and towing through insurance too for the motos but haven’t needed it yet
Engine cut-out also happened to me 2 months after taking possession with 4,200 miles. I went WOT with high speed traffic on the freeway then "click", had to pullover on the fast lane side and wait for DNA roadside. Blown fuse was my culprit, dealer replaced fuse and haven't had an issue since.
