1989 Starting problem

I have a 1989 F250 with a 460 fuel injected engine. The truck starts great cold but struggles when it is warm. I replaced the fuel filter, air filter and plugs. What else should I be looking at???

My 87 5.0 was doing that too. I had Napa check the battery just to be sure but it was fine. I replaced the starter and all is well. Mine got so bad that after it reached operating temp. I would have to let it cool for about 20 minutes before the starter would turn it over again and it was getting worse by the day. It could be the battery, cables, or the relay but most likely its the starter. Napa can test it for you, they did for me. Oil and grease build up around the starter mount are can mess with the electrical too.

If it is turning over then I wouldn't replace the starter either. I just misread his post, for some reason I was under the impression the starter was dragging. Sorry about that.

^^^^^^^^ was not talking about the starter, was talking about the stator in the distributor cap, part is old gets heated= fails, means kills the engine, lots of fun moving at about 75 mph and then nothing, or siting at a light knowing its comming but ya dont know when lol
