Buddy of mine has an 03.5 rev that he's having a funny issue with. From the way he describes it, the sled will run pretty good for the first couple hours he rides and then all of the sudden it will not rev past 4k and will die on him or cut out. It was doing this last year at the end of the year aswell but not all the time. Yesterday, once it started it would not come out of it and he had to be towed out. Anybody heard of anything like this? I had a similar issue but it would happen from the second the sled was road, ended up replacing the whole wiring harness. I was wondering if it was a stator problem but once again, it should do it all the time, not just after it's been rode for a while....
