my truck has been "missing" and sounds like it is about to die while idling. I have had it dealer last week for an oil change, belt replacement, and spark plug wire replacement (1). What is going on? Is it the fuel filter?

Your truck will run a lot better with new plugs & wires. As someone else said, there is no distributor cap on the 5.3L like there is on the old 5.7. They have "coil on plug" or whatever it is called. Ah, technology!
P.S. I had new plugs & wires done by a GMC dealership just before 100,000 miles and it made a huge difference in how the truck runs.....but it still eats too much gas.
