Why does my Nikon D7000 change shutter speed by itself in Manual mode?

On my Nikon D7000, the shutter speed changes after each shot even when I’m in Manual mode and the scene hasn’t changed. The aperture stays the same, but shutter speed makes large jumps on its own. I’m also seeing inconsistent exposure in shutter-priority and aperture-priority modes between shots under the same conditions. Is there a setting that causes this, and how do I turn it off?

Check if you have exposure bracketing turned on. That's the only thing I can think of that would cause that.
If so, it will cycle through a number of exposures, then back to your original setting, and repeat.
There should be a Bkt button on the left side of the front of the body as you look down on the camera (if it's the same as D90). Push that in, then rotate the rear thumbwheel and set it to 0F (again based on D90, might pay to check your manual)
Failing that, you should be able to reset your camera to factory defaults by pressing two buttons (which have green dots next to them) simultaneously and holding them for two seconds.

The most likely cause is exposure bracketing being enabled. On the D7000, bracketing can make the camera take successive shots at different exposure settings, which would explain the shutter speed changing dramatically between frames and then eventually returning to the original setting.
Check the camera’s bracketing setting and turn it off (set it to 0F / zero frames). On Nikon bodies this is usually done with the BKT button plus a command dial. If you’re unsure, check the manual for the exact procedure on the D7000.
If that doesn’t fix it, try resetting the camera to defaults using the two buttons marked with green dots and hold them for about two seconds.
So: this is probably a setting, not a defective camera.
