Why is my Audi car experiencing loss of power while driving?

I've noticed that my Audi car has been experiencing intermittent loss of power while I am driving on the highway. It seems to happen randomly and there are no warning lights on the dashboard. What could be causing this issue? Is it something I should be concerned about?

Based on the information provided, it is possible that your Audi's fuel pump may be failing. If your car is struggling to accelerate or maintain speed, it could be a sign of a weak fuel pump. It's important to get this checked out by a mechanic as a failing fuel pump can cause further damage to your car.
