1993 Chevy Silverado V8 Two Wheel Drive Automatic 150xxx miles

truck dies and won't start. Has to set for 20 to 30 min, then runs about a block and dies again. I have replaced the fuel pump and filter, rotor, cap and wires and oxygen sensor.

Do below and let me know asap

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, cap and rotor /distributor pick-up coil, ignition control module, ECM, Ignitor cam and crank sensors- Note: If it doesn't apply disregard it
