mine has done it too, but only when i have pulled the tether killed sled when on boost.
if this happens i remove my helmet, pop the hood and take a 15 min break letting everything cool down. if i do this it will fire right up after the break. first time it did it i pulled that thing over forever and could not get it to start, finally was getting ready to tow back after letting it sit for awhile and she fired right up. ever since then, i do the above mentioned, pop hood, let cool, have a drink and a snack, then its ready to ride again.
as others have stated, ALWAYS let sled idle down for at least 10-20 seconds before shutting it off, if you do this it will always start. at least on mine..

one of the quirks of owning a turbo sled....
