That sounds to me like a hydraulic problem.   Low fluid, as was
suggested..or perhaps a leaking clutch cylinder letting air get in and
clutch (brake) fluid get out.   If it did just get low somehow without any
obvious leaking...you may have to add fluid and bleed the air from the
system...
  I just recently  encountered that on my 84 and it turned out to be the
clutch slave cylinder....
