After filling tank with fuel, vehicle stalls at idle in gear. After burning 1-2 gallons it runs fine. No Codes
Does it do this if you leave the gas cap off?
One thing that comes to mind would be the fuel may be contaminated. I have seen this when excessive moisture(water) is introduced. Because gas tends to float above the water. So once the bottom couple of gallons of mixed/contaminated fuel gets burned off it runs fine. You could try re-fueling at a different fueling station.
