sounds to me like intermittent joints/board cracks.. this sort of thing 
happens to people's gear when they play lots of gigs.. bouncing around in 
the car wobbles all the parts slightly, so then the solder eventually 
fatigues and cracks, or sometimes the board does too.. also can happen with 
repetitve hitting with a stick.. I'd suggest getting a torch and shine thru 
the board, look for cracks.. if no cracks, the resolder the joints and this 
should fix it..
Cheers,
Dan
