Welcome to the forum Rob!!
As said above, if you haven't seen any leaks it sounds like a HG issue.
Mine was doing the same thing with the exception that mine was puking coolant under load. After 3 trips to the dealership, a new radiator and upper and lower hoses I had a second dealership looked at the truck and they said it's a HG hands down. After it was torn down sure enough it was a blown HG on the #5 cyl. I hope yours isn't the same but it sure sounds like it.
If you want/need a good dealer to look at shoot me a PM and I'll send you the info. It's going to be a drive for you because it's just north of Atlanta but they do good work and they know their chit. If you're out of warranty I can send you the info for a shop around here that also knows their chit.
