Question about Cars & Trucks
I had an Isuzu that had a faulty air sensor that caused a similar problem. When my check engine light would come on the car ran like new, because it would compinsate for the error message. But for the first 6 months of the problem the computer was not recieving an error when there actually was one. The problem is it could be anyone of dozens of sensors starting on combustion and ending at the last exhaust sensor. I would start by checking the connections on anything touched when the service work was done. If the problem is similar to mine you will also notice that your (mpg/kpg) fuel efficiency has decreased with the loss of power.

The cheapest way to go is to change the fuel filters first and the air filter. Then I would change the crankshaft sensor.
You may have to bit the bullet , and have the fuel pump changed before the fuel injection pump. The fuel pump in the tank can be loosing pressure to the fuel injectoin pump.
I think the lesser cost is the fuel tank pump vs. the fuel injection pump.
The system runs of fuel and air. No spark like on a gas engine.
So the problem can only be lack of fuel or lack of air getting into the vehicle air induction. A restriction in fuel or air will make the engine run poorly.
