Angry Hesitation at speed

I own a 2010 Focus SEL with 50K miles on it. I am noticing a slight / subtle hesitation while at speed. I can be doing 50MPH, 70MPH, cruise on or cruise off and I feel a hesitation from the engine. It is as if it is windy out and the car is buffetting slightly but is is not windy. It is also something that is more recent.

The engine idles perfectly.
( I am current with oil / oil filter and air filter changes)
If I bring the engine to 2500 or 3000 RPM it seems very smooth.
Since this began, I have also noticed an occasional roughness in the engine at start-up that smooths out right away.

When it began, I called the Ford dealer and asked if the car had a fuel filter that could be changed and was told "No". Is that correct?

Any ideas? ? ?
