I have this same problem, it has happened about 10 times now, 6,000 miles and three trips to the dealer and the last time to the dealer They had it for a week and a half. Dealer has not done any work on it they are only trying to duplicate problem I even ask them to let a tech drive home and around town still no luck, they stated they had opened something with Chrysler to see if they have any reports. The dealer also told me that they could not dig into the physically without Chrysler's approval without voiding my warranty, now I know they are not planning on doing anything for me. This is my first Chrysler product and will be my last unless they at least try to fix this.
I have about 20 years of experience with drive-ability Problems and know i could probably fix this in one day or less, but since I am retired now and the truck is under warranty I should not have too. It only happens while on a rough section of road or while turning left, We have a intersection at a railroad crossing and this is where it happens most. That only leaves a couple things it could be either a shorted wire, loose connection, loose ground or maybe even a bad ECM, I remember back in the late 80's GM had a lot of bad boards in their ECM's, you could tap on the side of it and it would either die or sputter.
I am now retired, disabled and don't have the equipment anymore.
When the weather gets better I will get out and check the wires and connections.
Anyone figure this out please let me know and if i find it I will post the fix on here.
BTW I checked all the fuses under the hood and found all the larger ones not plugged in good each one popped into place when I pushed on them, I thought that was it till it did it again yesterday.
