there are three bolts to the right of where you put the oil in that hold your slave cylinder in. if they are lose the clutch will work for a few seconds until the vibration push the slave cylinder back and causes the clutch to engage. ie tighten the 3 bolts holding the slave cylinder in place. that is my guess. the worst thing that could happen is you made sure your bolts are tight. good luck.
