This has been a really strange anomaly. Every time I go to fill up at my local favorite Shell station (and my tank is almost empty), the pump keeps stopping after filling about a quarter of a gallon. It stops at least 5-10 times within the next gallon, and after a while it keeps pumping all the way up until it's full. I haven't seen anyone else cursing and shouting at the pump like I have, so I'm wondering; could this be an individual vehicle issue? Is there some kind of sensor that could be going bad?
