Won’t stay idled after I put gas in it

Pull the codes.

@ Neuron is right for the place to start but is it the same gas station?

Consider ruling out a charging system problem before changing any "other" parts.

Quitting for an unknown reason but restarts easily is a prime symptom of a bad battery or loose battery terminal.

Next rule out an intake vacuum leak.

Then start looking for an EVAP system problem.

Question. When you fill up and the pump shuts off do you EVER add more gas? If so it's possible there's raw gas in the EVAP charcoal canister. Why is this important? Because excessive gas vapors will be drawn into the motor during an EVAP purge.

Often once gas gets into the EVAP charcoal canister it is ruined as the raw gas turns the charcoal to solid jelly.
