Any of the above you listed would probably not cause a cut out.
Is it complete, ie, there's suddenly NO engine output? That's
sometimes a fuel pump cutoff because of overboost.
If it's more of a violent shuddering, that's sometimes a big vacuum
leak or other similar problem affecting mixture; under boost, a hose
with a crack suddenly opens up and leaks a lot of air, boost pressure
drops, the leak closes, boost builds, etc. I would pull the codes
from the ECU and look for a big vacuum leak...check all the clamps on
the intake system, they should be very tight. Remove the
intercooler->intake pipe hose, clean it up, inc on the outside, and
bend/pull it every which way to look for leaks. Usually the most
common leak location is on the bottom side of the hose, where oil
pools in the folds.
