I had a 2000 dodge Ram 1500 I think it was 4.2 and did exactly the same but that one used to turn off and on right back on itself.when I was in low rpm’s. I sold it and bought a 2012 1500 5.7 4wd outdoorsman. Worked well for a few years and then It started doing the same thing it just shuts off when I stop in a red light when I am turning right or left in an intersection, besides when I am driving on the fwy it seems like the transmissions kicks really hard I took it to a reputable transmission guy he couldn’t find anything. Took it once to a dealer they couldn’t find the problem since there is no code. They told me the truck wasn’t stalling They replace the camshaft sensor, the crankshaft position sensor, spark plugs and pcm no luck still stalling, I insisted to keep it longer and keep driving it they refused to do so. So I’m thinking it’s a ram thing
Any advise would be really appreciate it
