When I first start the car the car runs with maybe 80% hp as normal but after about 30 mins pulling in first feels like I am in 3rd. Does anyone have an ideas as to what is causing this?
I appreciate any help.

Does it sound like it's missing?
Does it studder/fall on its face?
Any codes?
It's all about fuel, air, spark. Could be as simple as plugs and/or wires, or a clogged fuel filter, etc. Could be something harder to detect, like a broken valve spring.
