O.K. Heres the deal. I'm working on A 88, F-250 pick-up truck. It starts up fine when it's cooled down. When started and run for A while, and shut down, it won't start. Like the battery is dead. I replaced the silionoid, and the battery connections. I can remove the posotive side of the battery, and it still runs. I even cleaned-up the connection on the starter. I know it has to be A thermal problem, I think. Why else would it not start, after it's warmed-up. Runs fine otherwise. If you have any ideas, please tell me. Maybe the starer? Electronic ignition module? Oh, the volt meter reads on the dash, that it is charging at 14.3 volts, give or take. Which should be in the norm. Bad wire? Bad connector? Does anybody have any ideas? This is driving me nut's.

Just a thought, but maybe when it gets hot the fuel line is vapor locking and once the engine cools the vapor turns back into liquid in the line.. try isolating the fuel line from any heated parts of the engine.

Just a thought tho.

If it simply doesn't turn over, sounds like starter to me.
If it cranks but no fire, problem is in the ignition circuits.

On the distributor the is an ignition module you will need a 5.5 mm socket to remove it that is your problem.

Depends on what you mean that once it is hot it doesn't start.
An engine that will not crank over when hot may bave a problem with the solenoid, or ground wire from the battery. On a Ford the solenoid is separate from the starter. (btw don't remove the positive cable to see if the vehicle still runs)
If the motor turns but will not start when hot you need to find out if the vehicle loses spark or fuel.
