I asked you guys a while ago about my 06 500sp not wanting to start after being rode for a while took to dealer and they checked it out no faults showed up tha ecm wasn't one of the call backs but sure enough went up into the moutains in fairmont B.C. rode off and on for about 1.5 hours stopped and then the quad would start so how shitty to get towed down the moutain by a can-am but we stopped after about .5 of an hour and it started and I rode it the rest of the way down very puzzled on what to check next thanks for your advise in advance

 

this happened to me one time on my scrambler, what i did was take the hoses off the fuel pump one at a time to make sure that it was pumping fuel and it was tried to start it and it started just fine. dont know if maybe if it got vapor locked or what but never had the problem again (but bought a spare off ebay just incase).
