If the 2003 Focus is running good then suddenly shakes and looses power, check the fuel system for proper pressure. If the pressure is correct, check the ignition system for fire, the ignition components could be starting to fail.

What would cause a ford focus cut off while driving no power?

A Ford Focus cutting off while driving and losing power could be caused by several issues, including a failing fuel pump, a faulty ignition system, or a malfunctioning sensor, such as the crankshaft position sensor. Electrical problems, like a weak battery or loose connections, can also lead to sudden power loss. Additionally, issues with the engine control unit (ECU) or fuel delivery system may contribute to this problem. It's advisable to have the vehicle diagnosed by a professional to determine the exact cause.
