Ok mechanics out there, I have a 1998 Chevy half ton and I'm having trouble with it running. Truck will start and drive for about 15 minutes and then it will just stop, can not start for about 2-3 hours once it cools down will run again and them same thing once it warms up it stops.then next time it will run and start 10times over and for hours it will run.
I have changed alot of things it it already, would it be something electrical or something else.
Have put in new battery, alternator, module, wires, plugs, fuel pump pushing 60lbs, condenser is good. Any info would be appreciated

 

Maybe you did but check the relay on the fuel pump. Sometimes it gets too hot and shut it down... If not then would be ignition. Something electrical in there in the ignition.
