It runs fine on the freeway and just normal driving but when I start getting into it the fuel pressure starts to rise then drops around 20psi

What pump do you have on the car? Make sure electrical connections to the pump are good as well.

If your using the a- motive fuel filters, take them apart and check them.We've seen some cars lately that the filters are getting plugged up.Evidently the ethanol and the adhesives in the filters don't mix.The adhesive in the canister gets eaten by the gas then plugs the filter.
