What is wrong with a Briggs and Stratton engine that wont start after it has run for 15 min but runs fine until it is shut off and works after cooled?

One possibility is that the engine is running too rich. When you shut the engine off with no spark present the excess fuel present from the last couple cycles is flooding the engine. This would dissipate after time. Try the idling screw first ajust until the engine is about to cut out and then turn it about 1 turn back and see how it runs.You could also adjust the Pilot screw a tinybit toward the leaner side also. If this doesnt help then the float could be slightly sticking. Of course it could be some kind of screwy grounding problem. Hope this helps.
