How to troubleshoot engine failure in a Ford Mondeo?

My Ford Mondeo suddenly stopped in the middle of the road, what could be the cause of the engine failure and how can I fix it?

Based on my experience, it could be a fuel system issue. Check the fuel pump and filter for any clogs or damage. Also, make sure to check the ignition system and electrical connections.

It could also be a problem with the engine sensors. Make sure to check the throttle position sensor and the mass airflow sensor. Those are common culprits of engine failure in Ford Mondeos.
