2012 Power Wagon 5.7 Hemi. Turns on fine…rev’s up….when I let it idle it just turns off. Any ideas of the cause?

I have 64000 miles. I did just fill up with Shell. Why would Shell be a problem?Really is a guessing game. Any codes? Hook up a scanner to get live data. Great suggestions above. Could also be dirty fuel. Did you happen to fill up with shell? How many miles? Could possibly be fuel pump on way out. One thing that you can do that can be a easy fix is give the throttle body a good clean. You may just have a light ring of buildup but that is all it takes to start causing issue. Really take a look around the mid section. A toothbrush and some carb cleaner should be all you need and may actually be the issue.
I did just change the battery a few weeks ago…remote start wouldn’t work. After changing battery it started fine. What’s the impact of a new battery?IF your battery is low or has just been changed, it could just be a dirty throttle body and it hasn't learned how far open it has to be for idle. You can pull of the large hose and just look into it and see if it is really dirty or not.
If it is and cleaning it fixes the issue then that is a cheap quick fix.
Possible problems get harder from there.
