if the truck is running lean the plugs are not to blame nor will changing them help.I don't know what the codes mean so i can't help that way. but if you have a lean fuel mix try changing the fuel filter first. then stay on the fuel path not the spark path if that doesnt work

The codes you are getting are not pointing to the plugs. I am not saying they don't need to be changed soon but that is not the cause of your stall currently in my opinion. I have to agree with Dano follow the fuel route first.
How long has this been going on for and was there anything that you did differently before the problem arose?
How many miles are on the truck?

Sounds like something got picked up off the bottom of the tank when you got low and has now partial blocked your fuel line. Maybe the injector is clogged or something. Try adding injector clean out and see if that helps.

When was the last time that you changed the fuel filter...these trucks can have a very finicky way of showing they don't like the fuel. do you have any mods on your truck? IE CAI,Exhaust? Everybody has pretty much covered everything. I say do what Coskid says as well as a Fuel Filter change.
Just remember that not every gas station maintains their tanks as well as they should. I had a buddy that worked for a major fuel company and delivered fuel to stations. Older stations have small particles in the bottom of the tanks and when they refill the tanks the particles are just "stirred" up and viola they are in your tank. So try not to run down to the "LOW FUEL" warning in your truck to minimize the chance you pick up the nasty crap at the bottom of your tank.....
Good Luck with resolving your issues.

This could be pretty far-fetched but did you hit a large bump or bump into something recently??? I called a buddy of mine who had his truck stall on my ranch road about a year ago....here in TX, or at least at my ranch, we have 'caleche' (clay/stone) roads that lead up to the gate...They are purposely "riveted" causing an extremely rough ride if your vehicle isn't equipped with the right equipment (basically no passenger cars) to drive down the road. After we finally towed it to my garage in the ranch we checked the fuel stop switch located above the fuse box. It was activated for some reason. So if all else fails...check the fuse/relay that controls your fuel pump and the emergency fuel shutoff switch. Maybe that speed bump set it off......
Again far-fetched but maybe it could be a problem.....Good Luck....
