Buick Roadmaster Fuel Filter

I Drove My Car For 25 Mins On The Highway, Let Of The Gas And Pressed On The Break For 2 Seconds At A Stop Sign An Pressed On The Gas Again...

The Acceleration Is Slow And Also When At A Stop Applying Break, Car Turns Off, Was If Fuel Needs Replacing Or Should I Be Thinking...
