2003 Chevrolet Van fuel filling

I have trouble with putting fuel in the vehicle, it won't allow me to put fuel in at a regular rate I can only use a gas can or at the pump I must run it in at the lowest rate. When fueling the pump handle shuts off as if it is full even when I know it is not.I have replaced the evap. Canster selenoid with a new one it did take fuel at a regular rate for a very short time 2/3 minutes. Its very time consuming and cant waste my day stopping to add fuel 5 or 6 times. Any help will be appreciated thanx Tim.
