What shooting mode are you using?

Custom shooting modes can do what you describe.

Does the camera go into sleep mode when this occurs?

It happens during operation.

Strange, mine will default back to the original settings when the camera sleeps if I don't save it to a custom function.

Have you called support yet. The care team is pretty good at diagnosing and resolving issues but you need to register the gear prior to calling.
