Does it happen at all stations/ pumps ?
The reason might be a build up of pressure in the tank, so when you fill-up, the nozzle detects the pressure / fumes and stops pumping, thinking the tank is filled to the top. The problem likely will be in the vapor venting system, maybe an issue with the canister, lines, or the purge valve..

If it only happens at one station it may be that the flow rate at that pump is set too high. If it is set too high the vent system cannot handle the flow and the pressure will back up the fuel coming in and shut the pump off at the nozzle. Try to hold the lever at half flow and see if it works. Your system may also be partially saturated with gas and causing the fuel vapors to back up. Never try to get the last drop into the tank. Once the nozzle kicks out do not try to force more fuel into the tank by clicking the lever. If the pump is working properly and your venting system is in good shape your tank will be as full as it is designed to be.

I'll try again as I only got 3 gallons of gas before I gave up.it would not flow fuel for more than 3 seconds and a time and I just left

Even if it works holding the lever below full flow it will be aggravating and I know I would not be happy and not likely to return. If you have other options it might be best to stick with them. If the station is convenient or you like it I would check inside to see if you can find out why that pump is set like that. Maybe you can find someone with a clue and get it adjusted or report it and see if it gets adjusted. The pumps are mechanical and can go out of wack from time to time and the staff may not be aware of it. It drives me crazy when it happens, which is not often fortunately, because I stick to one Shell station locally that is well run.

Sorry for not responding to this thread long time ago. So my problem was solved by replacing Charcoal canister. It's under rear bumper right side. Need to remove wheel and wheel arch liner. First I removed canister let the pipes laying there freely and went to gas station to check if that's the problem. Sure it was. So only option was to change it. It can't be opened to change charcoals. By blowing with mouth it felt normal but there was some resistance. So mistake what I did was filling up gas till the nozzle kicks back 3-5x times couple of times filling her up. That's soaked up charcoal canister and clogged up.
