I have an 06 450 and for the most part it runs great. However, this morning I was at a race, it started fine to go check in. started fine to go to tech. When it was time to go to the line, it wouldnt fire. Kicker, button- nothing! We pushed it to try to start it (manually pushing it), nothing. Tried kicking it again on to the line I go. Starting fine all day untill I stop for gas and nothing. Got pulled by a quad and it fired instantly. Im at a loss here as to what to look for.
