When I had problems like this (many years ago, with my PZ-1p), the problem was a borderline contact between the lens and the camera. Hold the lens just the wrong way and the "A" pin didn't make contact, so the camera took a shot or two with the aperture set to f/32 (I usually shoot in Tv mode, so the shutter speed was fixed as well).
It took me a while to figure this out, but nowadays it should be much, much easier - look at the EXIF entries to see what has changed. If the "A" contact is suspect the lens information code will switch. If, on the other hand, all the EXIF value look reasonable you may have a lens that is misbehaving (a sticky iris, perhaps).
