What did you fix?

More info please. What engine do you have, new, rebuilt, old, etc. Does it have headers? What did you fix? Has anything been done lately to the engine? How hot does the engine get?

Just a couple ideas: Do you have the proper fan shroud? My Nova would reach 220 until I put the proper shroud on. Now it stays aroud 180. Also, if you run headers and they are close to the starter, the heat from the headers can make the starter slow cranking the engine over when hot.

yea headers close to the starter no good. Sometimes it wont even crank over.

I agree, sounds like the starter is getting too hot.You can buy an insulation cover for the starter to help with the heat issue. Or look into wrapping the headers to absorb some of the heat. That should take care of the cranking issue.
If you're overheating, try flushing the radiator, those old radiators can clog up easy and prevent good flow of the coolant. Also try a different thermostat maybe.
