What causes the Audi 80 to experience sudden loss of power?

I have noticed that randomly while driving, my Audi 80 experiences a significant loss of power. This usually happens for a few seconds before returning to normal. What could be causing this issue?

One possible cause could be a malfunctioning mass airflow sensor, which can lead to a sudden decrease in engine power. I suggest getting it checked by a professional mechanic.

Another common reason for this issue could be a clogged fuel filter. It is recommended to replace the fuel filter every 20,000 miles to prevent this problem.
