Is it an irregular surge? Does it go away when your using the cruise? If your a manual trans and it goes away on cruise, it's most likely your APPS.
Just went through the same thing, happens at a regular/ steady cruise speed, give or take 1800 - 2000 rpm, but disappears when cruise is engaged. I''m a 6 spd and the cruise is electronic so it's a dead give away when the APPS is taken out of the loop on cruise.
I don't know if the auto's are electronic cruise or vacuum but I'm sure someone will chime in.
Might be time for a Timbo APPS, way cheaper than the dealerstrip.
Also, fill in your truck specs so we know what your driving.

I had the same problems you did and did a ton of investigating and everything pointed to the pump.
But overall, my mileage never fell off, the truck idled just like normal, I had all the power I always had, it just had the surge.
I usually don't use my cruise on a regular basis and one day I did and the surge went away. A little more investigating and a few questions to people and it came down to the APPS.
I don't like to say or have people throw parts at a problem until it disappears but in my mind, it looks like you have a faulty/dieing APPS. You've replaced everything else in the loop anyways.
This is where you get the APPS from. Way cheaper than the dealer. Takes a couple of minutes to setup and your on the way. Incredible customer service also!! http://www.dodgecumminsapps.com/index.html
Hope it helps!
