plese tell me how and when this problem first began
did you check for spark at the plug wire?
tell me all you can
so it doesn't start after it cools down...?
does the starter seem to turn easier than normal?
first,replace the distributer cap and rotor,these can burn up on the inside sometimes and cause this...
the problem may be the ignition module,auto zone and most parts stores can test these ] these will break down with heat sometimes
