Thanks G2GBY. here are answers to your questions:
Last fuel filter change? - just before the trip
Air filter good? - Didnt check. Only 15,xxx miles. Will do, thought my mechanic would have check.
Have you cleaned your MAF sensor? No, I will look into this.
Is your rail pressure getting up to 29,000 psi? My mechanic will have to look into this.
I will google lack of power and see what I come up with.
What is odd, is that I seem to have enough power from 0 mph to 60. (getting on the freeway), just don't have any after that. Seems like I am driving something with a governor on.
