I have a 93 1500, 4x4, 350, automatic transmission. The truck starts just fine when it the engine is cold, but after it reaches normal operating temp and I shut it off, it acts like the battery is dead. I had the battery, alternator and starter checked and they are fine. It will start if jumped. The battery has 700 cranking amps. I have checked the ground and have cleaned the cables. It has a new starter and solenoid. I am at a loss. Any help would be greatly appreciated. Thank you in advance

 

That sounds like a bad or weak ground cable somewhere. The PCM might have one on those, might check for that.

 

I had this happen to me aswell and after 3 starters i found that it was just a ground cable

 

Recheck your cables and see if you got a bad ground connection. Also when is the last time you did a full tune up meaning: plugs, wires and the cap and rotor? Might want to check teh cap and rotor especailly and possibly a bad distributor. We had a distributor going bad on my mom's 89 Chevy Astor van. The distributor shaft had worn the bushing out allowing the shaft to wobble after it had heated up. Start with your cap and rotor see if it is corroded up.
