I Have a 2002 Polaris edge X. I have had this problem where the sled is shutting off after full throttle to hard breaking from the end of last season and this whole season. When I'm going 40 mph and slower and hit the brakes, it sounds like I hit the kill switch but the motor catches itself and keeps running. Any fast than that and the motor doesn't catch itself, it just shuts off. At quarter throttle, the motor misses, and when going full throttle to just letting off the throttle, the motor pops like it is back firing. The Jets in the carbs were cleaned and then it ran great for a day and then start doing it again. Does it with new gas, new plugs. It is not inconsistent either, every time from full throttle to hard on the brakes coming to a complete stop, the sled shuts off. Please Help.
