Since you have an 08 with less than 20,000 miles, I cannot believe it would be the MAF or throttle body. The fuel driver module is in front of your spare tire on a crossmember and you can see it if you lower the tire. Again, I would not suspect a problem there in an 08 unless you drive a lot on "salted" roads. If you do have a problem, it will have a "corroded" look and may appear to be distorted. If that is the case - replace it right now.
Again, a clogged fuel filter doesn't seem likely in 20K miles unless you fill up at stations where there's a lot of sediment in the gas.
Plugs & COPs? Maybe, but I doubt it.
Does the problem occur at all with the stock tune and, did the truck ever throw any codes? Possibly, there's a PCM flash update that would fix this and since you don't have custom tunes, it wouldn't hurt to ask your dealer about it.
I don''t see why Edge is referring you to PHP - they should only do that if you have a Gryphon.
