Clutch Hydraulic Pressure

I have searched through and read most of the posts involving the failure of hydraulic pressure in the clutch system and I have tried most of the 'fixes'. Sadly, I still have the problem.
Following mostly the advice from the poster, Gramps, I have attempted to bleed the system using both a vacuum bleeder kit as well at a Motive 'pressure' bleeder. I have replaced the master clutch cylinder. I am not leaking ANY fluid at all. The issue is that sometimes I can build the pressure but within a few hours the pressure is gone; faster if I'm able to drive it.

Everything I've read so far about the 'slave cylinder' says that when it goes bad it leaks (which, again, is not the case here). I'm not sure if this is an absolute or if it is possible that it could still be a slave cylinder issue. For obvious reasons I am hoping that it isn't.

I could try to bleed the system again -- but it just seems very odd that I can bleed and build pressure just for the pressure to go away again. I'm not seeing how bleeding it for a fourth time would make any changes. Though I will do it gladly if someone feels that this could still be an "air in the system" issue. I would just be confused at how pressure could be built in the first place. It would seem to me that air in the system would be a constant pressure fail situation.

I've been working on this problem for over a month now (granted taking some time for parts/tools to arrive in the mail). I am quite open to any ideas

Again, it just seems very odd that pressure can be built up after a bleed but then fade away with time. Also, while I'm driving and I can feel it fading I can sometimes regain pressure by pumping the clutch pedal -- this works for a little bit before the pressure completely fails though.

At the moment the Jeep is sitting with NO pressure and no amount of clutch pedal pumping will build any amount of pressure.
