It has a lot to do with the handle and the way it seals when you fill-up. If you look at a gas nozzle closely, there are 1-2 hole on the sides near the end. Its basically connected to some type mechanical mechanism that "trips" and shuts the gas off when the hole is covered like when the tank is full. Sometimes there is a little gas left over or something blocking that hole and shuts off the gas. Just go slowly at 1st before applying full pressure on the lever and you should be fine.
