At about 3 hrs my RK 25 started blowing the engine stop fuse and the engine quits. Unfortunately it runs immediately after replacing the fuse making it near impossible to troubleshoot. It runs for minutes to hours and then stops with the blown fuse. A quick internet search revealed a few of the same problems with no hard fix. Pinched wires frayed wires and a bad solenoid seemed to be the problem but no definitive fix or wire location. Does anyone have a good fix? The local RK mechanic has been out sick and not responded to my queries.
