My Monster shut down at about 65 MPH on the highway. I pulled to the side and it wouldn't restart. I checked the fuses, and checked and giggled wires, it started. I shut it off with the kill switch, it started. I shut it off with the key, it wouldn't restart, and nothing I did would solve the problem. I took it to Ducpond in VA (it was due for the 6K maintenance anyway). It was the ECU fuse. My guess is water worked it's way into somewhere and caused a short, but didn't blow the fuse until after I checked it. Next time I'll check the fuses twice. [bang]
