After driving my dads dodge ram ( 1999 1500 series 5.2 liter) it turns of after it warms up I guess. It will then start again after about 20-30 min. He changed the battery. He thinks it has somthing to do with the computer but i dont think so why would the computer go bad without it being touched? can some one please help! any input would be usefull.

 

Get a Fuel pressure Guage on there
I'll bet your pump is dying

any body else? before i do anything?

 

I side with JC, but a plugged exhaust will do the same thing.

 

I'd clean the throttle body & IAC motor 1st. these will cause the same problem, I had it on 2 mopar motors (5.2L & 5.9L) both times I cleaned the TB & it fixed the problem
