Hesitation at steady cruise, 2000 -2500 RPM

My 97 E300 D seems as suffers a pulsating Hesitation while attempting to maintain a steady cruise speed.

It feels a though the fuel supply is being interupted in a pulattion of about twice persecond.

It seem to be related to a steady engine speed with light throttle. Seems to occur at certain madifold pressesure, could this be a vacume pump problem ?
