Sputtering on 1996 Audi A4

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When I'm driving, the initial acceleration of the vehicle is fine but when I get up to 35-45 mph the car sputters. What is causing my car to do this?

You could have any of several basic problems regarding fuel or ignition. Try confirming fuel pressure as you accelerate , missing or sputtering accompanied by falling fuel pressure could be as simple as a restricted fuel filter.
Failing spark plugs or cables are a possibility as well.......
