Get a compression test. Seriously. One of your cylinders (the one that
it stops on) very well may have low compression. Something has changed.
I'd check it out.

That's what I thought at first, but how come it stops in the new place no
matter whch cylinder is coming up on compression? And if a cylinder is
really going, how come I can feel compression on each cylinder as I swing
the prop?

I've had soft cylinders before that caused the prop to stop in an unusual
position; this doesn't seem the same.
