This is a faulty fuel pressure sensor on the common rail. you can drive it fine as long as you don't put your foot down too hard, then suddenly the engine cuts out and you get a red light on the dash with a stop message. you can even quickly turn the engine off and on again and it will clear until you floor it again.
Replace this and the problem is gone.
