Another thought, the "rack" part #4 of the rail assembly on page 33
may be stripping & getting out of position on the screw, which would
throw the limits off. If it changes suddenly I would suspect this part
would be the problem more then the limits. If the limits are moving it
would probably be a gradual change.

Look on page 34 which shows the limit assembly (all the models are the
same).

Vibration isn't going to cause them to move that much. As I stated
earlier something is stripped or it may be the limit contacts are not
snapped onto the threaded screws completely.

I understand. I wondered this, also. The limit screws are fairly
stiff and I need to adjust them almost the exact amount of turns each
time (2+ turns). I'll look more closely and mark their positions to
see if vibrations are causing the trouble.
