The thing that stops the fuel pump / trigger is the presence of fuel backing up.
I have had this issue with different pumps on different cars.
Sometimes it depends on how fast the fuel comes out and at what angle the filler neck is.
Hold the fuel nozzle at a different angle and see how that goes.
Alternatively, if there is an issue with the tube that goes into the tank, it could be causing the fuel to splash back up tot he nozzle, making it 'think' it's full and cutting the flow
