Could you be accidentally pushing the lens release?

I don't think so... originally I thought that may be it, but I've been watching for that and am pretty sure that is not it.

Do you think the zoom movement could be doing it? The lens zoom ring has some resistance and I'm now wondering if the zoom in/out is somehow rotating the lens out of the camera mount.

The lock is in the camera, so any turning of the lens should not release it unless there is a problem in the camera.  Maybe the locking pin/mechanism in the camera is worn.  Have you tried mounting another lens and see if you can get it to turn without pushing the release button?
