My 2002 F12X is doing the exact same thing. But when we pull the 30 amp fuse it will turn on...BUT it won't stop unless you pull the fuse again. We disconnected the main switches to the dash and reconnected. It started and stopped...But again once the screen goes blank from non-use it won't work unless you disconnect the switch again. I called a Honda Dealer in Northern VA and they have no clue, nor does Honda direct customer service. If you find a fix please let me know. We think it may be the ECU which is $1299.99
