Yes I have it happen twice. Take the cover off the head cover and check where the main wires (the coiled ones) connect. They had put some light weight male & female connectors in there and they would get hot and not make good contact. I solved it by putting a round connector on the end of each wire then used a small nut and bolt to connect them. Prob solved. I hope this helps. I also thought my motor had gotten water in it but it was the wires.
