I was out for a ride, going down the freeway at about 75mph, and then all of a sudden I loose all power and the bike just shuts off like a light switch. It's a 2003 ST1300. I was able to coast safely to exit and tow the bike back to my house, but now I've got a dead bike. When I press the starter button, the engine seems to cranks over, but it doesn't fire up. I checked all of the fuses and none of them are blown. I'm at a loss. Again, it was running fine with no problems and just "shut off" going down the freeway. The lights work, horn works, etc. Any ideas?!?!?!
