I was going to mention that as the KX450 has had issues with braking fuel pumps on hard jump landings were the fuel pump/gas tank hit the head hard enough to break the fuel pump. Get your pump tested to see what pressure it's at.

yea thanks everyone and we checked the kill switch it was fine. But finally figured out the problem. We moved the gas tank back and heard a rattle so we emptied the fuel and my fuel pump broke inside and was in pieces in the tank.

I was thinking the same thing...I've actually heard a lot of stories about broken fuel pumps.
