Possible scenario. #102 is at the back of the motor mount, If it came loose the back of the motor would drop, the front would raise, and take tension off the drive belt.

I tend to agree with you. However #106 is the motor bracket. Screw #102 holds the back end of the bracket. If it is loose that my allow the back end of the motor to drop slightly loosening the belt. The OP didn't say but, I would think both screws would have to loosen for that to happen.
PS Ron. You beat me to it.

So maybe one dropped out and the other was about to drop.

We won't know unless the OP replies.

Those brackets (106,107) hold the motor in the headstock. Loosening that screw allows the back of the motor to tilt, reducing the drive belt tension.

That is exactly the correct answer. That's how you adjust the motor to either tighten or loosen the tension on the drive belt.

So, I turned for about an hour and it bogged down again. The second #102 bolt had backed out about 1/4". Added threadblocker to the bolt and reinstalled. Unfortunately, the belt must have stretched a bit, so it is still bogging down. Tomorrow morning I'll reread the manual and tension the belt. Has anyone gone through the process of balancing the belt tension?
