I can start it up and drive it a few miles and come home and park it and it ran fine. get back in it about an hour or two later I get in it and it starts running rough spitting and sputtering when I try to accelerate it bogs down and wants to shut off. It doesn't do it all the time about every 2-3 drives.

This sounds like the engine has a misfire or the fuel pump is going out which both can be intermittent. Can I ask if you have a check engine light on? If so this can tell us which problem you are having:

If the tune up is okay lets check the fuel pump pressure, you can rent a gauge set from the auto parts store for free. Here is a guide to help you get started with image below to help you with your truck:

(49.2 psi +/- 5 psi) at idle

Check out the images (below). Let us know how it goes.
