Question clutch problems help

I have a 93 wrangler with a brand new clutch and after 1500 miles roughly it quit working almost completely one day I had to shut it off put it in gear start it. with the clutch pedal pushed to the floor it would just sit and idle and seamed to function normally on take off but to shift I had to get the rpms just right (kinda have a talent for it my last jeeps clutch was out).
I did some digging and found out that it is a self sustaining system so the only way to bleed it is to pump the hell out of it. this seemed to work for a while no problem shifting into gears but now a few weeks later I have to pump it a couple times to get into 1st and even more times to get into reverse unless I go into 5th then down to reverse.
I cant figure out how it is good one day then bad the next pulled slave and it didn't seam to be leaking fluid but cant figure out why this is happening.
bad clutch master cylinder?

any help is appreciated

Air still in the system or is getting in somewhere. New slave cylinder?

I guess there could still be air in the system but I think It would get better and stay better not get worse again. it is not a new slave cylinder but if I was getting air in there wouldn't it also lose fluid too? its a 94 tranny with the slave on the outside.
im just trying to avoid buying parts I don't need (cash flow) is there any way to test it?

I had this same problem. My master cylinder was leaking All over the place and I eventually had to replace both the master and slave with it prefilled with fluid and everything. Was about $75 if I remember correctly. But that fixed my problem because I couldn't figure out how to bleed it and pumping the crap out if it with the cap off didn't seem to work even though it bubbled and bubbled.

ok now I have a parts jeep but it has the slave cylinder on the inside of the tranny this one you can bleed but what im wondering is.... is the clutch mastercylinder the same on both systems or is there a difference because I notice a wet patch on my firewall where the clutch mastercylinder is located. I could easily swap these two but if its not the same ill have to buy new...
It does seam to be working better now but everytime I hit a mud pit when I have to stop and back up (to rock back and forth) my clutch will never work I always have to pump it. it just doesn't make sense why it will work fine with regular driving but when im in 4x4 it works like crap.

(I have noticed this while accelerating quickly. I have to double clutch to shift otherwise it just wont go into the next gear)
