Thank you, that's great info! I was reading it could be either of those things so was considering replacing both.The same problem occurred on my 2013 months ago. First time happened in accelerating above 160 km/h. Second time hundreds km later when rotations went through 2600, later already through 2200, then 2000 rpm... After plenty of reading decided to have changed fuel filter and Fuel Pressure Sensor (BOSCH 0281006188) and engine shut downs solved
Hope it helps cause I suffered weeks..
