Focus Diesel Problems-Car Lagging

Hi just looking for some advice or if anybody else has had this problem.

I have a 58 plate Ford Focus Style 1.8tdci and am having some power problems when the fuel tank is at a certain level.

When I fill the tank the car runs smoothly for the first 100 miles then problems start occurring. When accelerating at around 2000-2500revs the car suddenly looses power and judders, it doesn't cut out but if I take my foot of the accelerator it will ease off and I can then accelerate a bit more then the same problems.

When the fuel then reaches 1/4 of a tank the problem stops and it runs fine again.

Appologies for going on a bit first time on here and slightly baffled with the whole thing.

    Change the fuel filter anyway & run several tankfuls of good quality injector cleaner through the system as a cheap-ish next step & see if there's any improvement
