little bit more info required such as year of car,mods done to car,what fuel cut level the FCD is set at etc.
Has the weather been a lot colder where you are?

yep sorry was a bit vague its a my96wrx all ive done to it is full system headers back,air filter,fuel pump,boost raised a little and a fcd fitted the boost was raised and fcd fitted at the same time both turosmart parts fitted at a tuner in plymouth has been running like that for about two years no probs
it has got a little colder within the last couple of days although it was warmer when it done it first
have put a different maf senser on and changed the fuel filter but it still does it

do you have a boost gauge fitted? and how was the boost raised? if by a manual boost controller then it might need a clean and re adjust.i think 7 on the hks fcd was the recommended one for the impreza, not 100% on that tho
