That sounds like a problem with the Hall Sender. It could be as simple
as a wire in the system losing contact momentarily, to the Hall Unit
actually becoming faulty. Cheapest route to start is to check out all
the wiring first, including the quality of  grounding points. You may
have some corrosion building somewhere or a wire working loose.
