Hello ,. Im Bobby .
I think you fuel shut off solenoid is bad, You can unbolt the solenoid from the engine and turn the key on and off and see if the plunger is working. Also check the current going to the solenoid , if there is no current going to it, then there should be a fuel shut off solenoid relay somewhere that could be the problem.
Well I am pretty sure it is located on the right hand side of the engine when you sitting on the seat, it is held on with 2 bolts.
