Try to stall while fueling

Try to stall while fueling
Ok, this spooked me. I'm sitting at a gas station about 1 this morning..Temps about 60 degrees. The car is warm so I left it running while I got gas. I started the pumps and had but a couple of gallons in and it tried to stall. The RPMS dropped way down, but then they went back up. Is there any possibility that the fuel temp was much cooler and it hitting the tank froze the fuel pump for a split second? I've never experienced a drop in rpms like this before.
Any thoughts?

Only way I can see that happening is you splashed enough bubbles around the pump and the fuel injectors treat bubbles just like gas, so no fuel for a split second.
....but I agree, a seriously bad life-decision to fuel up while running.

Keeping the car running while fueling up is a bad idea and illegal in many areas for a good reason. While liquid gas is going in the tank, explosive gas fumes are being forced out. Any spark could cause these fumes to ignite. A shorting or loose spark plug wire, the brushes on the alternator or many other sources could be the flash point. Please turn the car completely off when fueling. I will even if it is -20 F.
The reason for the stumble could be due to the engine running with the gas cap off. This could throw off the emissions system sensors and the PCM.

See, now this is why I like it here...Thanks guys. Of course I know your not supposed to smoke at or near a gas pump but I didn't know something like an alternator spark or lose plug wire could spark an explosion. Lesson learned, and my mind eased.

Half the time, I dont turn it off bc I fuel up like 100 feet from my place and my car isnt warmed up yet, so I let it run while I throw 15 bucks in and grab my 44oz coffee

If you take the gas cap off while the motor is running, the PCM will register and evaporative leak and initiate a bunch of countermeasures that amount to a huge vacuum leak.
Mine will stall if I take the gas cap off when its hot.
Next time you fuel up while its running, be sure to wear some rayon and rub a balloon on your head while talking on the cell phone.
