Anyone had a pickup coil failure on a VKpro ? Our 07 at Wolverine here in Ironwood will run for about an hour, then sputter for 50 to 100 yards and shut off. Let it sit for a half hour and it starts right up and runs fine. When this happens there are no warning lights flashing, no overheat, just shuts off. Unit has overheated often before we had second radiator installed,which is why I suspect pickup coil is breaking down.
