i noticed my truck hopping a little bit when starting out in first and then it drove fine.When i went to start it it had no clutch pressure and my clutch fluid was all gone in a matter of a minute or two.any ideas?

 

Find where the fluid went. Fix the leak.



All there is is the master cylinder (could be leaking down the firewall inside the engine compartment or inside the cab), the line to the release cylinder, and the release cylinder. The leak is somewhere along the way.
