I have a Bandit 1390xp. Starts and runs great. Dies after a little while. Fires right back up no problem but keeps dying every few minutes. It's as if someone just walked up to it and turned the key off. No smoke. No noise. Just shuts down. Help! I need to fix this ASAP! I had a similar situation last fall where it would intermittently die but would only start some of the time. I replaced the key switch and it worked great the rest of the season. Could I have another bad key switch? The chipper sat unused for 4 months over the winter in NH uncovered. Maybe water got in it. Or is it something else? Has anyone had this issue?
