I had similar problem last summer.
Stopped the rig. Would not crank again.
I learned mine has an ignition solenoid (that activates the engine related fuses).
It also has a starter solenoid.
I accidentally (after 4 frustrating hours) tested the ground connection of the ignition solenoid and found it was no longer working. I have no clue as to what caused the change by just stopping and turning off the engine near my driveway.
I improved that ground connection and all has been well since.
My ignition solenoid is in the chassis fuse box in the driver side front basement. Of course, you may not have such an animal.
