Sending unit going bad. Easy to replace.
I guess I should ask first, when does it happen? Going down the road, coming to a stop, only when the engine is warm?
Mine used to do it only after Hwy driving than coming to a stop. So, I replaced it. My new one only lasted 9 months. So, I'm trying to decide where I want to put a mechanical gauge.
