Last night I was on the highway, I went to pass someone and the car downshifted and pulled to about 4000-4500 rpms and then kind of evened out and did not want to rev higher. Stopped at a red light later on and punched it through 1st gear and same thing happened.
I checked the valve on the end of the fuel rail and it barely had any pressure, cycled the key and still not too much pressure. I know it should be quite a bit of press. i'm thinkin at least 45psi
Question is could a bad FPR cause the power loss at higher rpm's?

Fpr?

Yep, sure could, but it's also the classic symptom of a clogged fuel filter or a fuel pump that's getting really tired.

fuel pump is 2 weeks old (walbro 255lph)
I will change the filter tomorrow
With a fresh pump is it good to change the filter anyway (particles and such from new pump)

Never hurts. I would change it out with the pump. New pump could also be defective - unlikely but possible or like you first suggested could be the fuel pump regulator, but you should have 40 - 44 PSI of pressure at the rail. You also have a test port between the filter and the tank which you could use to test for a clogged filter.

Same thing happens to my XC. After I put a set of Samco's and silicone lines on I thought that I may have missed something. I still am getting P0171 for a code
but the cars "stalls" @ about 4k. I was thinking that when the relay failed, it failed. Nothing intermittent.On that note, how do you test the relay?
