When filling up car with gas pump will cut out.

I beleive you have a evap hose issue or an issue with the rollover valve in the tank. You need to take it to a shop and have them perform a smoke test in order to diagnose this concern. The evap system on this vehicle is involved and consists of many hoses, valves, and lines, this is not something that can be diagnosed without extensive knowledge of the system and the correct tooling to test it.
