Car is turning off during the drive on the road, no matter what is the speed and rpm's. When try too start engine again fuel pump is soundless, because it is not getting power. I am able to start the car only just if pump starts making some noise.
Could you tell me how to resolve this issue?
Thank you!

Also, check fuses and relays under hood see if you have blown a fuse or a relay is not turning on pump.

I have found out and established that both fuel pump and everything related to electronics is working properly. As well, fuel pressure regulator is working-class properly. What else could cause thar car turns off and stops working while driving? Why it needs much time to get started?

As well, one more thing that is odd is that car has strength and it's pulling forward really well, but again, sometimes, all of a sudden, turns itself off without any sign of engine choking

What is your fuel pressure? Also check battery for condition including load test. Because this is a 2.0L turbo we have no specs on this car as it is not in USA

If someone checks the fuel pump when it is working it will be okay, still could mean the fuel pump can be bad though. They fail intermittently.

Please let us know what you find so it will help others.

Best, Ken
