Are you sure the fuel pressure is not dropping off at higher revs?
Could be a number of things. Obviously your not delivering enough fuel to the engine, so you either have an injector problem, a fuel pump problem, a fuel pressure regulator problem or blockages in the fuel lines somewhere. Or maybe a sensor problem.

Not really got alot to go on. If you haven't changed the fuel filter in a while that would be a good place to start.
