Mazda MPV Diesel reports error P00200!

Hello all, I hope you can help me. Since about 1 month our MPV spins, he suddenly goes into the emergency program during the ride and then turns off only 1,500 rpm engine, 5 minutes wait and continue the ride. How long this goes well is different, between 8 km and 80 km we have already experienced. The increase to this error is the exit of the engine during the ride. The workshop has read the error, it is called P00200, injection nozzle – circuit error. Cleaning of the nozzles as well as a cloaking of a cast cable did not bring any improvement. Yesterday he went out 3 times in a row on a distance of 15 km in a construction site! Does anyone know the problem and if so, how to fix it? For your efforts I thank you in advance, because we want to drive the MPV to Croatia next week.
