This is an addendum to the original message:
I brought the car back to the shop that put in a new clutch, slave cylinder, master cylider and tube and they flushed and put in new hydraulic fluid and bleed it. It now works most of the time. My guess is that the master or most likely slave cylinder is not functioning properly. Any other guesses before I bring the car to the Nissan dealer form which I bought it from and they charge me my right arm and left leg.
