Need help!!!2000 mxz 700

[skidooracing3]

i have a 2001 ski doo mxz 700 the other day i put new plugs in it and if ran fine, today i started it up let it warm up and when i took off i fouled a plug, so whatever i put a new set in and it ran fine...getting on down the road it shut off, i thought it was maybe the teather switch or just the kill switch, but i cant quit figure it out, because it will die out, and i can start it up in one pull, and it runs fine again until it dies. sometimes it will run for 10 minutes and sometimes it ill run for 5 seconds, i cleaned the carbs and have tried diffrent plugs again but still think it is coming from the kill switch is the only thing i can think of....someone please help me....thank you
