Tow vehicle: 2010 Infiniti QX56 Trailer: Searay 240 sun deck. 5500 pounds Lately, when I am towering and hit any type of rough road, I get a front and back push and pull going between the truck and the trailer. I have surge brakes. Accelerating or braking will not stop the tug of war. Never had this issue before. Vehicle has self leveling air shocks that are working fine. Surge brake on trailer is also working. What is causing this?

My first thought is that perhaps the boat is not fully secured to the trailer and that is causing some movement. You will also want to look at the trailer tires and suspension for wear. Replace any worn out parts and make sure everything is tight light it should be.
The trailer tires should be inflated to the maximum psi rating as indicated on the tire sidewalls.
You mentioned that the surge coupler is working properly but it would be worth it to examine the shock to determine if it needs to be replaced. If you can move it in and out by hand then there are some worn parts that you will need to replace.
You also may be experiencing sway that feels like a push/pull from the truck. The solution is to add sway control. Since you have a boat trailer this usually involves a pole tongue adapter, like # RP58393, and a Reese SC weight distribution system like # RP66153.
