Perhaps its time for a clutch change?
Check the master and slave for any leaking as well as ther hydraulic lines. If there are signs of fluid leaking, replace the offending part. If all looks good, bleeding the system and inspecting all bushings and linkage as stated by Markdas is a great place to start. If bleeding does not solve the issue and all the bushings and linkages are in good shape, the only other alternative is to remove the transmission and inspect the clutch components.
