Thanks Mr. EMills!
This is a good point. I could not have moved the car +/- 7 feet without hitting the rear wall and the garage door.I think it was more like 2 or 3 feet I moved before it locked up. But if the input pinion was stopping on something (pin) it wouldn’t even make 1 revolution of the pinion, which might be 1/3 of a tire revolution, which might be just a couple of feet. (It turns freely now continuously in either direction).
Yes, it is limited slip, and that was locked up by sitting a couple of years ago and made a horrible racket when I tried to turn (not unlike this current episode). I drained all the diff oil and put the correct oil in it with Mopar correct (for this limited slip) additive. I took it to a vacant parking lot and turned figure 8’s and it eventually smoothed out and has never been a problem since. That very well could be related. I agree about power testing until I understand the problem. It was suggested that I put it in gear on the jack stands earlier, but I didn’t for that reason. I am confident that although I may have a failure somewhere, I haven’t done anything to break it-yet.
When I get the driveshaft back in, I will try pushing it back and forth and see if it locks up. It did stop squarely in both directions, the rear wheels seemed to lock up simultaneously. I wasn’t moving fast so nothing skidded-it just stopped immediately. Real immediately!
I have both a transmission jack and a floor jack. I am accustomed to using the floor jack for dropping my Jaguar IRS, but this center section is a much smaller chunk so I may have to strap it to the tranny jack.
I really appreciate your help!

One revolution of tire would be about 7 feet +/-. So if it goes about 6 to 7 feet in each direction before locking up, I'd be looking at something jamming up differential. Maybe less distance depending on what is broken inside. Is diff Limited Slip? I would be careful about further diagnostics under power - may do more damage. Does it happen when rolling car by hand in neutral?
Center chunk can be removed - heavy but can be handled - did it when I was a kid but would use something to support weight these days - smarter and not as strong.
If one side only, maybe brake on that side, but I doubt both brakes would lock up at same point. Push with steering wheel turned - then repeat opposite direction - is it different left vs right?
If you are ambitious - disconnect drive shaft and push - does it still lock up - if so you have isolated to diff / axle / rear brakes. But I'm leaning that way anyway. Broken tooth or pin jammed in ring gear as someone else suggested would be my bet.
