Cruise control changes speed after going at set speed for a while
When I set my cruise control, it will stay at the set speed for a while, then drop it 5-10 mph. I have the 5.9L engine if that helps.

That's typical of a vacuum leak in the hose going to the cruise control servo, or in rare instances, a leak in the servo itself.
