I have a 1992 Chev Blazer S-10, 4.3, 200,000 mi, auto transmission.

The vehicle will start when cold, but once it has ran for a period and you turn the vehicle off, try to restart immediately, it will start. However if it sits for 10-15 minutes it will not start and continue running. It will eventually start after it has set for a while. Periodically cuts out when first accelerating.

Have replaced plugs, wires, distributor cap, rotor, ignition swith module.

Sounds like vapor lock, but that shouldn't happen with these electric fuel pumps, so I would guess and say it may be a low fuel pressure problem. Check the fuel pressure and if low then replace the pump.
