Yes, and you'll laugh when i tell you. Unless you're not as sad as me, of course... 
I read between the lines a bit there and assumed you were out for a good b-road thrash. When you're smashing it through the gears at full throttle the engine obviously draws more fuel, but normally this is all well within the capabilities of the pump. Now, when you hit a right-hand corner particularly hard the g-forces mean all the fuel fecks off to the left-hand side of the tank, the problem with that being the lift pump is in the right-hand side of the tank... This means the pump is briefly starved of fuel, rail pressure drops as a result, and bingo - lumpy running/cuts out and p0230 fuel pressure code.
Used to happen to me all the time until i worked it out, easiest way to avoid it is to just put at least half a tank in before you go for a serious drive. So yeah, don't worry about looking for a bigger problem, because you'll most likely be wasting your time and money.
