The engine continually stops running while tilling. It doesn't sputter or cough just stops. This is not due to overloading or anything like that this is a problem with the machine itself. We use high test gas, it won't run without it, and the filter is not dirty or clogged. Starts easily and idles well just won't stay running when you try to use it. Had this problem almost from the beginning and got no real help from dealer. Machine is about 3 years old.
