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.
