I have about 25 hrs on my Cannibal and for some reason this weekend after an hour of riding everytime I switched into third and tried to get on it, it stalled. It felt as if I was out of gas. After a few stalls it ran ok (a few sputters here and there). Although, the next day I fired it up and left it idle for a about 5-7min (warm-up time) and it stalled out. Has anyone had a problem like this. Any feedback would be helpful. Thanks

 

Sounds like the fuel filter. Have you changed it yet?

And also check your chain slack. Might not do it while idling, but last year at High Point a Cannondale kept stalling on the track and they determined the chain was loose. The quad has a sensor on it.

 

It has a chain slack sensor? wow.

I bet fuel filter too. I never let mine idle more than a minute or two without feathering the throttle.
I've also never fouled a plug.
