Dodge Grand Caravan gas tank won't continuously fill

We have been having an issue with our gas tank not filling up continuously for over three years. It automatically trips the gas shut of switch every couple of seconds so it can take a while to fill up. Then every once in a while it fills up totally normally. Any suggestions?

We need to know what is the model year of this Dodge Grand Caravan. If it is a fairly late year, it is possible the problem is in the Onboard Refill Vapor Recovery system.

Let us know and we may be able to give you appropriate advice.
