On a couple of occasions when I first started using the Pentax 67 I was not threading the leader deeply enough into the spool slot, not winding it sufficiently to build tension. The result of this faux pas was that the shutter wouldn't fire and there was no wind-on! Some films also do not have a punched hole in the leader (unlike Fuji-san), and this makes for quite a fiddly exercise without having a piece of masking tape to stick the leader in place, especially if you happen to discover the take-up spool itself does not have a 'tang' in the slot to grip the hole in the film leader! Always carry a small amount of tape for quick fixes!
If there is no doubt the film leader engagement technique is at fault (and that is what I think), the other thing that comes to mind is a broken or worn/slipping winding pawl (when the cameras have been through many years of quite heavy, day in, day out professional use, the winding mechanism is usually the first thing to fault). If it is intermittent in nature, you might be able to make-do and get on with it. Otherwise, not being user-serviceable, an enquiry can be made to Eric at pentaxs.com
The frame counter roller, that slender tube to the right of the film gate, may be suspect.
Like others have said, I would also check the battery, and especially the battery compartment for any signs of corrosion.
