Lost the pressure on clutch. Bled the line worked fine for 2 weeks. Went out again. Changed the slave cylinder. Still not clutch. Goes to floor won't engage. Changed the master cylinder. (old one showed signs of leaking) Tied to bleed the line. Still no pressure. Cutch stays to floor. Any suggestions? When I follow the line from the master cylinder to slave cylinder looks like the line goes into another part then the line goes out of that part into the slave cylinder. What is this other part and could it be my problem?

Your only problem is that you have air in the system. Attach clear plastic tubing to bleeder screw, having it drain into a Coke bottle. Push clutch pedal to floor so that brake fluid will flow through the hydraulic system, after you open the bleeder screw and remove the top to the clutch master cylinder reservoir. Pour fresh brake fluid in the reservoir, until all the old fluid and air are purged from the system. Close off bleeder screw, replace top to the reservoir, and pump clutch several times. After you know everything is working properly, make sure not to fill the reservoir over the MAX line.

An alternative is to use a Cal-Van One Man Bleeder, which I use every 2 years to change the fluid in my brakes and clutch. However, you have so much air in your system, at this point, that I'm not sure it would work well for you. A power bleeder would be ideal for you at this point.
