Keep on burning Fuel Shut Off Solenoid, PLEASE HELP

I've had a few gators but all gas except this latest one, a 6x4 diesel and I love it. Lately it keeps on burning the Fuel Shut Off Solenoid (M806808). I've checked the voltage going to it and it is between 13-14.5V with engine on. Seems normal to me, so only other issue is too much current is going through to it. What is the current limiter to this solenoid? Please help.

Thank YOU!
