So I have a 2012 Ram 1500 5.7 Hemi with 103,000 miles, starts fine, runs great, but if you hard stop the engine will kill
All electronics stay on but no engine or power steering.
Dealership change ignition switch, any help would be appreciated.

 

Will it restart right away?

 

Yes restarts immediately, no hesitation.

 

Last time the throttle body was cleaned?

Getting any codes?

 

No codes, shot some carb cleaner in it yesterday, still doing it.

 

Is there an Idle air control valve?

 

No, drive by wire uses the throttle for low idle. Common causes for stalling when hard stop are the torque converter not disengaging or a vacuum leak.
