I just shot 4 rolls of kodak gold 100 for a friend's wedding. After
developing at a local lab, the first two rolls turned out, and the
last one also came out well, but the third roll, only the first 4
shots came through. The rest of the negative was blank. The edge
markings (Kodak and frame number) was there, but the frames were all
blank. Does this mean that the Kodak film was inproperly
manufactured? I don't think it's my camera (Pentax PZ-1 SLR) because
the counter still counted, the motor and the mirror did not sound like
it was stuck, the last good frame in the negative was NOT black
(multiple exposures of the same frame) and it rewound properly at the
end of the roll. It's not the developer because the negative edge
markings developed properly. The pictures were shot outdoors on a
sunny day and I did not adjust anything on my camera for any special
settings.
Anyone experienced this before?

There could have been a problem with the flash or automatic exposure. If the
edge markings came out, it is not the film.

I can't see how the edge of the film was coated with emulsion and the
center wasn't. If there was a wavy nature to the fault I would agree
with you.

Most cameras (well, all of _my_ cameras, a small sample of all
that are available) keep on clicking even if the film isn't moving -
much to my disappointment and embarrassment.
> the last good frame in the negative was NOT black
Now that's unusual if ripped perfs or stuck film was the fault.
> it rewound properly at the end of the roll.
So it most likely was not low batteries.

That happens to me: I didn't _knowingly_ adjust anything ... but that
doesn't sound like the case. Your camera doesn't have a 'blank film'
setting, I assume. I suppose setting the ASA to 6400 would do it,
it may be in the DX contacts - are the negatives _completely_ blank,
exposing 100 film at 6400 (six stops off) would have recorded
_something_ very faintly.
> Anyone experienced this before?
Similar to this, many times. Exactly this, no.
It sounds to me like a transient fault in the camera. Could be it's
got some Windows code in it - did the finder turn blue? - just a joke,
but cameras these days are run by software and software invariably has
bugs.
And one can also blame the problem on Gamma-Rays -- they are one
remaining cause of errors in computers and can't be gotten rid of. The
reliability of some circuits is high enough that such rare events can
be seen. 30 years ago it was alpha-particles causing errors in RAMs,
but that was because the epoxy was slightly radioactive.
There is a chance that it will never happen again, but there is the
chance it will. Typical help center response, eh? Try again, maybe
it will go away.
[Ob joke: A salesman, a field service rep and a programmer were driving
in a car when a tire went flat. They got out of the car and looked and
pondered. The salesman said "We need a new car." The field service rep said
"lets swap all the tires around so we can isolate the bad one."
The programmer said "Let's come back tomorrow, the tire may have fixed itself
by then."]
FWIW: A gamma-ray with 45 ft-lbs (3.8E20 ev) of energy has been recorded,
or so I think I remember I read. Seems pretty remarkable to me, it would
seem that the detector would have been destroyed.

Hell's bells, that's not a subatomic particle, it's a fastball!

Stuck shutter.
