Dead Ignition - 2018 Wrangler JK 3.6

[compass]

Hello all,
Thank you for all of your help in the past which I found by reading past posts. This on has me really stumped.
Driving in traffic on a Mexican freeway the jeep stalled. My wife got it started again for a few seconds and that was all she wrote...
Dead dashboard and no crank.
Jeep has a strong battery with robust and tight terminals, starter cranks fine with a small jumper lead.
Here is what is throwing me, when I remove the 10 amp fuse M27 ignition Sw the dashboard lights up again. I turned the key on and cranked it with my small jumper lead to the starter but no start...
Error codes;
P0302 cyl 2 misfire
P0113 air intake temp hi
U1402 custom error code
U0002 can data bus hi...
This happened once before 3 months ago but while! I was scratching my head with the ignition on the dash came back to life.
Thanks for any advice the jeep is in my driveway in Mexico now

Is the small round red dot lit up on the right top of the dash cluster? If so it could be your key FOB battery is bad, that's the security system.
