Takes longer to start when cold.Loses speed rapidly on cruise when going uphill then surges hard to get speed back.Sputters and rough idle. Sounds like backfire when driving. Could this be the fuel regulator?

Check your fuel pressure. It could be the pump is going out or the fuel pressure regulator is bad.

Found my problem. The coolant tank was a little low sending a message to my oxygen sensor causing my engine to randomly missfire. Filled the coolant level up and problems stopped. Who would of thunk it?
