Truck dies after fill up on gas
Last two fill ups it has happened.
I start my truck after filling up at the pump. Pull out of the station, go a little ways down the road, stop at a stoplight. Sit at idle for maybe 30 seconds & the truck dies. I put it in park, turn the key, & it won't start. I let it sit for 10 or more seconds & it will start up. Don't have any problems out of it again until I fill up with gas. Then same thing happens.
Do I need to replace the EGR valve or what do yall think?

Common problem for the 2002-2005 trucks has been the fuel pump check valve going bad. Now that 2006-2008's are getting older and higher in mileage it seems we are having the same problems.
Unfortunately, the pump is an entire unit and must be replaced completely. It isnt cheap either! $350 or so.
I would try not filling it up completely and see if it still does it. Then fill it up more and more until it happens. Then you'll know the fill up point. It'll save you money, well, delay the inevitable..lol

Dog has my vote. Mine is starting to act up too, but I expected it might soon, sometimes start up takes a little more cranking than normal----but it is also due for a tune up. either way, I lost a pump somewhere in Oklahoma one time on a trip, it cost a bundle and 3 days to repair on my old Dakota, do it soon or we'll all hear you cryin in your beer.

my question is: is the check valve going bad a sign of a fuel pump that is about to go out? Thanks for everyone's helpful responses.

That sounds more like an EVAP related issue to me. The check valve in the pump will cause long start issues, since it causes the fuel to drain back into the tank while sitting, fuel level should have no effect on it since the pickup is in the bottom of the tank.
When you fill the tank, the EVAP system has to properly regulate the pressure of the vapors in the tank. If its not working properly, it can cause driveability issues. A common problem on full size chevy trucks pre 07 is that the EVAP vent solenoid malfunctions and causes the fuel pump to actually draw a slight vacuum in the tank. the aging pump fights the vacuum and loses, truck stalls.
I would advise taking it to a shop and explaining the issue to them, pay for a diagnostic, and have them monitor the EVAP data and check for anything out of spec.
Of course, there is always the aforementioned, dont fill it up solution...
