Curious about filling up tank with the truck running
i sometimes fill my truck up while running and when i do i notice when i let the pump run for w while then stop it ( to hit the desired price) the motor drops in idle, or when i am filling up and over fill it, it bogs down and soemtimes stalls, why is that,

Mine is really weird with this.
I can't even run it w/o the gas cap...I think my fuel pump is going bad.
I used to fill it up with the truck running all the time...no problem. Then one time I went to fill it up like that and took out the gas cap and it just stalled. I to this day can not fill it up while running. Weird

Not a good idea, due to evap reasons and static electricity would be my answer. Why would you leave your vehicle running while filling up? You're getting 0MPG while sitting there filling up, if it's because you just like to watch your gas gauge then just leave the ignition in the "ON" position and it'll work exactly the same as having the engine running. BTW, Has anybody ever heard of the horror stories of static electricity causing fires at the pump? Do a google search if you need more convincing.

Why fill up with the truck running? Your truck is off for a max of 5 minutes, if that, and the air temp on the inside won't drop that drastically.
Like BJ said, if it's for the gauge, just leave the key on, but turn the truck off. Or better yet, why not just wait until you get in the truck to find out how much gas you have?

Its the opposite...it's hot out. I always used to fill while running, I stopped doing it after my truck wouldn't stay running...now I'm against it after I saw a few videos...sucks it took that for me to realize it though

Yes and he'll be the one getting the heat for doing so if it were to start a fire. Why 'add to the fire', to sort of speak?
To answer your question, research your truck's evap system, i'm willing to bet it has something to do with why you are experiencing what you are.

Leaving the truck running is not a fire hazard. Some people seem to have evap system problems but other than that, there is no danger in leaving it running. Cell phones aren't a fire hazard either despite what the internet says.
Static electricity from getting in and out of the car and fueling cans in the trunk or on plastic bed liners is a real fire hazard. That's about it. Oh, smoking too. That's not a good idea either.

When i was selling cars we had a few trucks on the lot that had dead batteries and were running on fumes. We would jump them and drive to the gas station. But the batteries didn't recharge enough to start the car back up so we would leave them running when we put in a few gallons of gas. But aside form this situation I see no need to leave your vehicle running.

The Vapor Management Valve is attempting to purge the canister using engine vacuum. When you leave the fuel cap off during purge, it effectively creates a large vacuum leak that can cause a rough idle or stall.
Every gasoline pump has a sign that tells you to turn off the engine while refueling. So does your owners manual.
