hydraulic clutch line issues too much pressure?

Ok, i have a 1994 ranger 2.3. so i've replaced the whole clutch, from the master cylinder down including the line that runs from the master to the slave, i'm still having problems with it but this time it seems to be losing pressure randomly or in spurts whenever i hold the clutch in too long it will simply lose pressure and start to engage, it is also losing fluid out of the line connecting the slave to the master cylinder (where the visible leak is) what could cause this to happen? i want to say it's the reservoir cap that has that pressure bag in it (rubber) that inflates whenever the master cylinder is pushed in to create that nice seal, but i honestly dont see that as a major problem of my issues. wouldn't be so bad but it's losing pressure and getting air in the lines every 3-4 days. which means i have to crawl through the ice and snow to fix it.

Update:

Edit: the line was factory, rubber hose except near the master where it's steel, no scoring on the slave cylinder and the slave was an aftermarket item, push it in till you feel the spring, get the C clip out and push it the rest of the way in and put the C clip in, not what ford wants but it seemed to work great and would be a lot easier to get off than that stupid quick connect line they used in the factory (plastic white sleeve push it in and its supposed to release, it didn't) now if i just simply pump the clutch, holding 1-2 seconds it wont leak at all, if you sit there for a minute or 2 it will start to engage, which leads me to ask why?

    When you inserted the lines, the o-rings may not have seated right and become damaged. This has resulted in a leak. Parts stores carry balk o-rings and you would need to match them as I am not sure that they show up in the parts books.

    Well it sounds like the answer to your problem is in your description of the problem. First, you have to correct and stop the leak......Any leak in the system will cause problems. Once you are sure there are no leaks, the system has to be bled of all air. This task is always been a problem on Fords and can take quite some time to do. We have often raised the front of the vehicle to aid in bleeding the clutch. After all leaks are fixed and the air is bled out, you should have no more issues...

    When you replaced the clutch pipes are they metal? like brake pipes or is it a flexible pipe with a screw in fix to the slave cylinder?, they metal pipes have to be flared to give a proper seal, check to see if there are any visible scores along the fixing point in the slave cylinder that fluid could run out of if it isnt properly sealed.
