you replaced the fuel rail pressure transducer? your tune could be messing it up as well as the pcm or wiring.

My first guess would be a fuel filter that's clogged just enough to max out the transducer for long periods of time. Try changing the fuel filter and checking the fuel pressure if it hasn't been changed since you started having this problem.
