No spark after Warrior runs for 10 minutes

[ettev]

Either at an idle or when riding after about 10 minutes our 2001 Warrior dies. No spark at the plug. Most likely culprit is what? Coil? Stator? CDI box? Some other switch/relay? After the machine sits for 15 or 20 minutes it starts again and runs for 10 minutes then again no spark. Help!!!

First, always start with the easiest thing; put a new plug in. I doubt if that's it but who knows, you might get lucky. Just off the top of my head, I would bet on the CDI.
