Question about 1992 GMC Sierra K1500
It can still be the fuel pump.the pump could be getting hot and not working. If u let it set for awhile and cool down it will start. You need to do a fuel pressure test it should read between 40 and 50 psi. Let it run for awhile and see if the pressure drops. If so I would replace the pump
