Welcome to JUST ANSWER small engines, let me try to help you !! When the engine quits, do you have spark? Check with a spare spark plug, remove the spark plug wire, attach the spare plug, and with it grounded, crank and watch for spark. No spark, your coil is failing! With this engine, the only thing that makes the spark is the magnet in the flywheel and the coil. If you have spark, then you are loosing fuel supply. I assume the fuel tank is venting and not drawing a vacuum on it.??
