1993 polaris sport 440 fan. It will start up normally, but then dies out. I am able to use the throttle to spin the track. it doesn't matter if I am on the throttle, or it is idling, the sled will just quit running in about 15 seconds.It seems to be a fuel issue. I replaced fuel pump, filter, and all fuel lines. Took carbs off and cleaned thoroughly. It started doing this on the trails with no warning. The gas in it is the same gas we put in 2 other sleds at the same time (I thought it might be water int he gas). Thanks in advance for any help
