Anyway, he replaced it and it worked like a charm. Now it started to do the same thing again, with the Service Engine light ON. I have to find out what part was replaced (anyone knows??). Also, anyone knows how to turn the Engine Service light OFF?

The part is called a Fuel Pressure Regulator. It is located on the fuel rail on top of the intake manifold. They are usually fairly easy to replace and cost around $50 from a parts store.
The main symptom of a bad regulator is that the engine needs to crank longer than normal (usually about 2 seconds or less of engine cranking is considered normal) to start after it has been sitting a while. It can cause worse, but not necessarily bad fuel economy. Sometimes it can cause the computer to store a P0442 (EVAP system small leak) code triggering the SES light to come on.
