Could it be your Pressure Plate, not your clutch?

Manuel,
    Your description sounds similar to the behavior of a collapsed
pressure plate.  The pressure plates I've collaped were heavy duty or
sport plates and suffered one total failure while yours might be
severeal smaller failures.
A visual inspection of a collapsed pressure plate will show cracks from
the vertices of the V points of the diaphragm spring where it is
stamped, running from the point of one or several V points to the outer
edge of the plate of steel that the diaphragm spring is stamped from.
    Possibly each instance of your problem is a new crack happening in
the diaphragm spring plate, and the plate pieces then shift back into
close enough position for the plate to work satisfactorily in normal
duty service for a short period of time until additional fatigue causes
another crack to happen in the diaphragm spring plate.
Good luck.
