Re: hangtime
Welcome to the forum.
You should have a overheat horn that will sound off if the engine overheats.
Sounds more like a fuel or ignition problem. I would start by checking to see if you are loosing spark when the problem happens, use an inductive timing light to check and make sure you have spark on each wire when the problem happens. Sometimes an electrical componet will overheat and cause problems, and when it cools off it runs properly again. You might also try pumping the primer bulb at the time it happens to see if you have a weak fuel pump.
