Could it be that you have so little traccion that the BLD/Traction Control is killing all power?

Try disabling the ESC completely. See if that does it.

BTW, engaging 4L will disable ESC.

Otherwise, there's a button on the lower center part of the dashboard.

Any warning lights, engine sputtering, etc?

no check engine lights, i called two dealerships today and talk to two different techs , they have not heard of any JLU jeeps doing this, they had no fixes..

This is probably a dumb suggestion, especially since I don't even know if this can still happen in modern cars/trucks & jeeps, but is it possible that it could be air or water in your fuel filter or line, or fuel pump? I had similar issues many years ago with an old truck dying after sudden changes in inclines, and if I remember correctly, it turned out to be stuff in the fuel filter.

It seems to me that the only thing that would cause it to die after a sharp change in incline like that would be a sudden loss of fuel, or spark. That was a long, long time ago though, and hell I might even be misremembering that that's what it was since I was not the most mechanically inclined to begin with, and I was even worse in my teens.

Anyways, hope you can figure it out soon, would suck to miss out on a trip like that!

How much fuel is in the tank, I just saw a video with a 392 going down a hill at a steep angle with a low fuel tank, it shut off at the bottom thinking it was out of fuel

Definitely don’t be afraid to yank that parking brake if you lose brakes and start sliding backwards!

Do you have off-road plus engaged when this happens? Off-road plus turns off quite a few nanny features which would help if it’s one of those you have scared. I’ve climbed and defended 30deg pitches in my 392 and the engine has never skipped a beat. I’ve always been in 4-Lo and off-road plus mode.
