Wondering if anyone has had this happen? My 2002 MXZ 380 will start and run excellent for about the first 20 minutes. Suddenly it will quit just like I hit the kill switch. Without touching anything it will start perfectly and run for a minute or so and then the same thing again. When it starts to die if I quickly toggle (push then pull) the kill switch, tether or key switch it will fire back up and continue on for another minute or so. I have tested the key switch, tether and kill switch and there are all okay. Anyone have any thoughts on this weird problem?
