Ron, I had a similar problem with a 351-C. It turned out to be heat soak problems with the starter--there just wasn't room for all the heat to escape in that little Mercury Comet (AKA Ford Maverick) engine compartment and the headers wrapped right around the starter, essentially baking it. Had it rewound by a racer shop and wrapped it with an asbestos (!?!?) heat "blanket" type wrap, problem went away. After that, I'm always suspicious of the starter windings when it happens only when hot.

OK, so this sounds too simple--how about some ducting aiming a cool air flow at the starter while you're running? Might be a cheap fix, might not, but a pretty easy experiment.
