The car is shutdown after few minutes, or during when brake press.
And the car is not powerful .

Hi,

It sounds like you may have a vacuum leak at the vacuum brake booster. The booster is mounted directly behind the brake master cylinder.

Check to see if the vacuum hose is leaking or if you notice a hissing when the engine is running.

Let me know.
