I have a 1988 f150 with a 302 in it. It
will not stay running. I can go outside
and start it up and it will idle just fine
for about 15 minutes then it just dies
off like its starving for gas. I've put
plugs and wires, drained any bad
gas, changed fuel filter, changed fuel
pump relay and I am puzzled does
anyone know what it could be?

Have you tried cleaning the throttle body with throttle body spray cleaner if throttle is dirty vehicle can start but when it idles down choke can not close all the way and sucks in to much air and shuts down vehicle.
