engine will shut off if the fuel pressure spikes too high.. Pro-steve had that issue with mine when mapping it.
White dieselly smoke indicates unburt hydrocarbon entering the exhaust...
seems like either: an injector issue, leaking or stuck injector?, or a rail pressure issue?
the cutting out would point to overpressure, especially if it is difficult to restart immediately afterwards for about 10 seconds..
check connections at rail sensor, remove the pressure regulator from rear of pump and inspect for any swarf on tip of pin. clean the regulator sensor clear codes and see how it goes.
Fuel pressure at idle should be (IIRC) 298bar... if you smoothly but quickly rev it it should go up to around 1300bar and stay steady under revs..
