I have a 2013 B3000 that suddenly does not start. I started it and used it for about 2 hours, when I stopped to get a drink I left the engine running and disengaged all drives and pto like I have done in the past. As I got off of the seat the safety shut off engaged and the engine shut down from about half throttle. I thought maybe I had left pto engaged and would shut it off when I got back on. After maybe 5 minutes I got back on and every thing was disengaged, when I tried to start it the fuel solenoid engages but the starter will not turn over. I have pulled out all fuses, looked good, I am at the end of my knowledge and need to use tractor this week because I am on vacation and can't figure out why it won't crank. Any ideas?
