Good question, any number of things can cause this, leaking fuel injectors, blown fuel pressure regulator, even some bad engine sensors can cause a problem. The first thing I would start with is the fuel pressure regulator as it is a known problem, to go any further you will need some specialized tools, ie scanner, pressure tester, ohm meter, wiring diagram, etc.
