Why has my Nissan Micra lost power?

I drove my 2003 Nissan Micra off of the driveway, it then lost power and stopped. It now won't start or lock and keeps beeping.
Possibly the mass airflow sensor, which was quite a common failure in these cars. Unfortunately it's buried in the throttle body and is difficult to repair, so a new throttle body is usually prescribed (assuming I'm right about the cause of the problem). More seriously, it's possible that the timing chain could have jumped or broken.
