GMC SIERRA GAS PROBLEM

1994 GMC Sierra • 175 miles

1994 GMC 5.7 Engine Missing/Surging/Sputtering, I started my truck this morning no problems then after idle for 10 minutes it just shut off, waited a few minutes started it up again and then put into drive went about 10 feet pressed on gas pedal to accelerate and truck died again? I have replaced the fuel filter, what else should I check or replace. Thanks for you help on this.

Check fuel pressure and check under tbi unit for a blown gasket causing a vacuum leak they are known for that. Also check hose to map sensor onfirewall for soft and sucking together or hole in it.
