Cutting out on booting it nothing to do with Crank Sensor. Crank sensor often doesn't leave a code when it goes as it just goes. Try the MAP which logs the boost pressure, you might just get away with cleaning it as its normally covered with carbon crud. If it doesn't cut out engine and just go into temp cut power mode, its the Turbo actuation side like operation of the gate actuator. Look for P0235 here.

Bad Crank sensor or ring  should activate EML - well it did on mine 2008 MK5 not 100% sure on MK4. 

 

Usually it is the valve at the end of the fuel rail that leaks under gigh pressure and replacing him usually helps for 2-3 years. 

+ clean or replace MAP sensor. 

+ clean EGR if you can (or block it) it will help. 

 

There was a very good video on YouTube while ago done by @@Andy from here targeting all areas of cut off problems.
