What readings do you get from the O2 sensors?
I have had similar symptoms with a failing fuel pump, from a cold start the rich mixture was fine but when it warmed up the leaner mixture was not rich enough to keep the engine smooth. I do not think it would run smother at higher speeds though. The fuel pressure was under 10 psi.
