I have a 95 GMC with th 5.7L TBI. When you re-start the truck hot, it will
start them innediatly die. Crank the starter for a while and it will
re-start with an erratic idle and then smooth out in about 10 seconds. It
only does this after sitting hot for 20 or 30 minutes after stopping the
engine. Cold start, no problem. Turn truck off and re-start in 10 minutes,
no problem.

help :(

I had the same symptoms on my 93 4.3.

I narrowed it down to the ignition module.....so rebuilt the distributor
(p-u coil, module, etc.) and replaced the cap, rotor, and rusty secondary
coil. So far, so good.

I'm pretty sure the main culprit was the ignition module......it did test
bad on the high tech testing machine at Advance Auto.

check pluggs for foulin wires for arcing and burned areas...cap an rotor
for carbon build up..check fuel pressure..9 to 14 psi with key on engine
off...check IAC..remove an clean...check TPS..then check for vacumm
leaks..replace cracked or dry rottled hoses..check EGR..quick diagnose
would be to plugg off EGR and see what out come is..still stalling EGR is
good..move on to ECT..engine coolant temp might be the culprit here..get
engine to opeeratin temp ..unplug the ECT..and start the
engine..drive..does it die..if it doesnt die then you found your
problem...
