My best guess would be starter heat soak. The solenoid is getting too hot, which will make the starter crank slowly or not at all. Wrap the starter and solenoid with a heat shield blanket. Thermo Tec is one company that manufactures them. They're available at most auto parts stores.
If that doesn't work, wrap the exhaust pipes near the starter with fireproof header pipe wrapping tape. That should be available at your local store as well.
A new starter would be my last choice if neither of the above work. You may need to buy a new starter, wrap it with a heat shield blanket and wrap the exhaust pipes as well.
My 1972 Road Runner drove me crazy with this exact same problem. The heat shield and exhaust wrap helped, but I still had to replace my starter every couple of years. The heat from the headers would seriously shorten the life of any starter I installed in it.
