How to diagnose and fix the engine stalling issue in Audi 80?

I have an Audi 80 and recently it has been stalling while driving. The engine turns off suddenly, and I have to restart it to keep going. What could be the cause and how can I resolve this issue?

It is possible that the stalling could be caused by a faulty ignition system. Check the spark plugs, ignition coils, and ignition control module to see if any of them need to be replaced. Don't forget to check the wiring and connections as well.
