2920 died while working no power

Hope to get some ideas.....I was removing some brush in my field when the tractor just died. No power, no click, nothing. Checked the battery at 12.97 V all fuses, seat switches and no love. Neighbor came over to help and used a portable battery to start it. But when it was removed the tractor died. Kept this up until in the driveway. Could this be an alternator issue? I have not load tested the battery so far. Always thought a motor would run without a battery once started. Thanks

The shutdown solenoid needs 12v to keep the engine running. Have you check the battery cables at both ends? Specially all the grounds? That's often where the issue resides.
