If you get it scanned for faults that will give you the answer, no good guessing the car will tell you what you need to know.

Just had the same issue with mine. Been diagnosed today as a Turbo issue after a long investigation. 

Probably best to first look at your Glowplugs as it could be the pressure glow plug which is failing. After that get it properly diagnosed. If it comes back as a Turbo Underboost fault then you are looking at a faulty turbo which will cost you about £2700 as I've just been quoted.
