Hope someone can help with a strange problem with my wife's TRX250TE ES. I can start the engine and it will idle until I run out of gas. I can shift in reverse and ride all day. I can shift into a forward gear and can go maybe 3-5' and the engine dies. This just started a couple of days ago and until then the unit has been bulletproof. It is a 2003 model purchased new in 2004. Any help would be much appreciated. At first I thought it might be a brake problem but that has been disproved.
