the AMM is a rebuilt unit from FCP groton with about 10 months and 10,000 miles on it, also when that acts up won't it usually throw a code?

can the crank sensor fail intermittently, i have asked the mechanic twice to check the fuel pressure. the FPR is new and the systems primes and turns off like it should when i start it. also can a fuel pressure (fuel pump) problem happen intermittently.

when it acts up if you accelerate from a low rpm to a high rpm at a constant pressure it hesitates at high rpm, but if when it starts to hesitate you push in more on the gas it will lose rpms.
