Answers:
you probably have water or moisure in the fuel line. when it gets hot, the water expands, and clogs the line...Change your gas, and blow out the line

Does the engine have a magneto? It might need servicing.

you have internal damage to the piston or valves more than likely. If you had no spark, it wouldn't start period. If you gapped the igntion module wrong, it wouldn't start either. The fact that it runs for awhile till its hot and dies and restarts when its cool is internal damage. But do try this first, change the fuel filter. I've had a mower one time run fine then die every now and then and it was cause there was crap in the fuel filter and would occasionally block the fuel passage.
