Our service team said, It sounds to me like the coils are going out on the engine, losing spark causing the engine to shut down. This would likely also cause a no start issue when the mower shuts down for at least a half hour or so after. Its best to bring it in and let our technicians check the unit out and test for coil failure. https://ope.buckeyepowersales.com/services/repair/
