Farmtrac 300DTC shuts off

[Slickwillie]

I have a Farmtrac 300 DTC that starts when you turn the key, but shuts off when you release the key. Replaced ignition switch, did not solve problem

Did you ever figure this out

I would suspect run circuit for fuel shutoff solenoid. Hook up a voltmeter or test lite to wire(s) going to the solenoid to see if you have any power on a wire with key in run position..
