Case 7140 problem plz help

I jus finished big baling and I was driving my case 7140 down the road. And out of nowhere it jus shut off it didn't sputter or nothing. It jus cut power. And all it does is crank over. But doesn't fire. I checked the fuel shut off fuses and there good. I switched around the relays and still does same thing. I holded open the fuel shutoff lever near the Fuel solenoid and still nothing
