I have cub cadet model 1330 with kohler 12.5hp. When I first start the engine, the rpm is not steady, it is like someone is reving the throttle up and down. After a couple of minutes the engine runs even at full throttle. Then after 15 - 20 minutes of full throttle, the engine just dies and will not restart. After a cooling down period of 5 - 10 minutes, the engine starts and runs full throttle for 5-10 minutes then dies again. Then the whole process of waiting 5-10 minutes begins again. My neighbor thinks it might be a burned out ignition module. Can you help please? Thanks, Dave
