Starts right up and then runs 20-30 minutes then shuts down, hit the button and starts back up but then only runs for a minute or 2 then shuts back down again. Someone said it was the alternator which put a new one on but still doesn't help.
It have oil pressure?
Yes it does
Code when it shuts down? 3 beeps?
No, as soon as it starts if you remove the fuel solenoid it will run find. Ran for 3 hours with no problem so replaced the solenoid which has the wires out the top instead of a plug, seems ok now.
