2003 Hyundai Santa Fe

Engine Mechanical problem
2003 Hyundai Santa Fe 6 cyl Two Wheel Drive Automatic

I have a 2003 Hyundai Santa Fe. Right after adding fuel to the vehicle it does not start properly. I have to press the gas pedal a good few times when that problem occurs (right after adding fuel) to get it started. After driving back from the gas station and take the key out of the vehicle the engine will " diesel" (idle) for a few minutes as well. I only experience these 2 issues only after adding fuel to the vehicle. I would think that if it were the fuel pump or filter (which are both in the tank) that it would occur more frequently. I'm very confused. Any knowledge and or insight is greatly appreciated.
