Albert, A lot of lawn mowers have a problem with the gas cap not venting properly and will quit running after running a few minutes as you described, try running with cap removed or very loose( be-careful of splashing fuel).

Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.

I have been fixing a JD 14sb with a kawasaki fc150v engine, it was just shutting off every time it got hot. It seemed electrical but there was always a spark. Turned out it was the igniter on the side of the engine which controls the timing of the spark. Took me a long time to isolate this fault. Hadn't come across this part before, thought the timing of the spark was simply controlled by the flywheel magnet passing the coil.
