What happens when you try to start it? Is the engine overheating? Please give us as many details as possible. Even ones you don't think are related.

Sounds like the starter is dying from heat soak.
Do you have headers?

Let me know how your can is set up, under the hood, because my 83 has been modded quite heavily and i don't have a problem with hot restarts, so I think I might be able to help you.

Boy, that's weird, totally stock, and you have this problem.
You are describing the exact same problem I had with my 79 T/A w/headers.
I would have to let it sit for 20-30- mins to cool down, before it would even turn over.
New starters never seemed to fix the problem, either.
I ended up useing 24v battery cables from a Caterpiller, and that ended my problems.

So I would say to first check and make sure you have very good-new battery cables(both of them).
This way you are getting the most amps from the battery to the starter.
Or you can make your own cables out of heavier gauge wire (similar to the gauge used for a welder) and see how that goes.

But to be honest, if you are 100% stock under the hood, I don't see a need at this time to get real crazy with changing a whole lot of things, as it may just be some minor maintainence/ tune-up items. But I would think about getting some new (stock) battery cables, if I were you.

Also make sure you have good secondary grounds...ie. engine to firewall, negitive post on the battery to the radiator support,,, that sort of thing.

Good luck.

Leon.

I had the SAME problem with my 91 305 TPI. The next owner (no i didnt fix it) told me he wrapped the starter with some header wrap and the problem dissappeared. Do what Leon said, tryout what I said, and let us know how it goes. Also, double check all your wiring, check for spots that the wires could be gettin hot and look for shorts as well.

This is simply called a "hot start". It occurs when the solenoid gets too hot. Check the wiring going to the starter ,considering you have already replaced the starter. The wires may have insulation missing.

Check your conections as heat goes up so does resistence. and if its the solinoid getting to hot you could always run a ford one.

I don't know man, I tried that on my 79, when chasing my problem, and that didn't help, either.
Go with heavier gauge wires.
That will never fail!
