2005 ski doo rev 600ho carb

Hi, I recently bought a 2005 rev 600 ho with around 6000 miles on it. I have already taken it on a trip to Michigan and have put on around 200miles without any problems. Then today I was driving back to the trailor and it started to bog down but still ran. I got it on the trailor and it started fine once I got home. When I applied throttle it bogged out again and couldn't hardly move forward. I tried to take it for a lap around the yard and it bogged at first then all of a sudden seemed to run fine, then shut off. I tried to start it and the dash and the headlight didn't light up at all. I messed with the teather and the kill switch for a little bit the tried starting it again. I got it to run for a second and then it shut off and now I'm not able to get it running and neither the headlight or dash light up. I'm thinking the problem is the teather or the kill switch, but I'm not positive. Thanks
