Are you doing your own processing? I had problems with a lab doing something similar. I thought it was the camera but the problem was replicated on another camera with the same lab.

Without more information it's difficult to speculate but it would appear that the film is advancing if you have images before and after the "missing frames." Are there actual images which are missing or are they appearing farther down the film with a space preceding them? If there are actual scenes which are not appearing despite having been photographed it would suggest a shutter problem - as in unexposed - rather than a problem with the insert.

The click may be the mirror... on the other hand it may be that the mirror is not being activated and is thus blocking the image transmission. It has been far too many years since I have worked with the Mamiya 645 for me to guess at what is happening. You should however be able to observe and ascertain what is happening but it sounds as if the problem is not likely the 120 insert.

Check the foam around the mirror. Onthe sides it can keep the mirror from moving and can be intermittent.
