When the power drops off and you pull off the road, does it idle in neutral OK?

Is it such that it just doesn't want to go when under throttle load and in gear?

It kind of sounds like a fuel pressure/delivery issue. I'd be inclined to rig a fuel pressure gauge to the injector rail and place the gauge on the cowl where you can monitor it while driving under all conditions. Weak fuel delivery can be hard to detect in the driveway when there is no load on the engine.
