SOURCE: Stalling
Possibly faulty ignition module is the problem, stalls when engine is hot when you sit for a while it cools off and runs again until it heats up again, those are usually the symptoms of a bad ignition module and after a while it may give out all together and not run at all, usually if the module is at fault it shuts down the fuel pump so the engine don't load up with fuel, do to when engine continuously cranks over the injectors never stop squirting fuel and flood the engine do to lack of spark which is produced by the module, this could possibly be your problem.

check your pmd switch. i had mine changed and it runs great. the problem is that it gets too hot and burns it up. be sure to move the pmd swith on the firewall away from the injection pump.
SOURCE: 96 gmc sierra hard to crank after 12-14 hours
that has a votec engine in it the fuel pressure is droping at knight and it takes 60 psi before the injectors will fire most likely cause fuel pump ,leaking injector ,or a feul pressure regulator
