Along with the pump shutting off (clicks) when trying to fill. Occasionally mine does this too. Sometime even when the tank isn't filled. Handle will click and fuel will over flow onto the ground under the car or sometime comes out through the inlet.
To avoid all the issues, I angle the handle to the side, swung clockwise. In addition I take my time filling up and use 1/2-3/4 of the trigger.
Never felt the need to pursue it. You may find your trouble will come and go as the seasons change.
Hope this helps
