Hi
Two things come to mind. First it could be not getting enough fuel when hot due to carb adjustment being too lean. That could be that the float level in the carb is set too low or the low speed jet is set too lean. When cold the choke circuit in the carb supplies the extra fuel required.
Second in some enjines that have low compression they start cold but when hot the compression drops below 60 psi and makes starting very difficult until engine cools down.
I suspect a fuel problem.

does it turn over slow or fast if it turns slowly thats the problem so it could be battery or starter they have to have a good amount of rpms to burn fuel right when starting if not it floods out the engine with gas hope this helps thanks wade

if it restarts immediately, check the vent in the gas cap for restriction. also, the solenoid on the bottom of the carburetor may be sticking or getting weak. if you have to let it sit for awhile before it retarts, the ignition module may be breaking down when it heats up. i'd bet on the gas cap or solenoid though

I had a similar problem and found that the float was hanging up on the wall of the carb fuel chamber. I sanded lightly the outer edge of the float and never had the problem again. That was 3 years ago. Having a different problem now. After setting overnight in cold weather, 20's, engine turns over very slowly even with a new battery. Engine starts, but barely. Once running, everything seems fine. After shutoff, engine restarts quickly. Next morning, same thing happens. Anyone have any thoughts?

Very interesting bob. Got me scratching my head! Maybe some sort of ground problem in tractor?
