Mine did this with a knackered dump valve. Once booted, it would keeo the valve open and create a massive air leak. I replaced that and has been sweet ever since.
If you havent a d/v fitted, i'd take a look at the boost hoses and make sure all jubilee clips are tight.... maybe on boosting the hose is expanding allowing air to be lost via a loose clip.
