2007 250ex problems

I have a 07′ trx250ex i’m having problems with it when I go down the road it shuts down. I have gas in it and once it stops I have to put the reserve on for it to start back up. I read that it could be the fuel filter.. I’m not sure if it is or even how to check it out. Is anyone else have this problem before if so how do I fix it. if you could please give detail, I never had to fix my four wheeler..only done work on my car…thanks:stupid:
