I also had a stop solenoid burn up on a tractor a few weeks ago. I used a piece of sting to tie it open to get it back to the house to get the part to fix it. A OEM listed for $280 and I found one online for about 30 so it pays to shop around, just had to wait a few days to get it. I have also had the fuel line stop up, I had to blow it out to drain and clean the tank. If the fuel filter has not been changed in a while it could also be stopped up. It can take several checks to pin point the problem.
