Been chasing a bug, long story short 2021 Ram 1500 Etorque. Engine/MGU, torque converter all replaced under warranty 500 miles ago. Was pulling a trailer and the vehicle shut down (not completely, felt like a dead pedal), came back on while rolling and popped a CEL U1885. Dealer thought maybe 48V pack but it dying didn’t make sense to them. I swapped 12v to an H8 AGM battery and I thought that helped until today was pulling on the ramp and it shut down, I noticed when it does this the voltage drops to 12.3 and will start to fall, everytime it shuts down I’m able to restart truck and drive normally.
Rear glass was fixed, RHF hub was replaced, only thing I can think of is another bad MGU, or a ground? Seems to happen under load but can’t consistently replicate.
