My 1987 TRX250 is in great shape, but recently has started shutting down after riding for 20-30 minutes. It sputters a little, and stops. The you wait a little while, full choke it and you MIGHT get it back to the barn on one shot. Usually two or three start/stops to get home. After a couple hours, its back to a full 20-30 minute run.

So I put a new coil/plug wire on it last week and it SEEMED to help a little, but still dies out. I thought the coil might be breaking down.

Next I suspect fuel delivery…maybe trash in the tank gets jiggled around and blocks the petcock?

Any ideas from anyone would be great!

Thanks!
