Monster won't start with "warm" engine

[JoeP]

Very strange. I have a 2001 M600 that starts fine when the engine is cold, and also right  after a ride when it's hot. But if I turn it off and let it cool for a half hour, it won't start. Nothing happens when I press the starter. I can wait a few hours for it to cool more, then I can start it again. Anyone know why it's doing this?

You probably have high resistance somewhere that builds with heat.  I would start first with the battery terminals and engine ground.  Don't just look, disassemble and clean. On the battery disconnect negative first, connect negative last.
