Clutch question

[bondo]

I've got a Bp in my car with the festiva trans and a excedy clutch. It's just starting to slip but at only certain times. I can feel a lost of power when it slips and when it's not slipping. Could there be another cause of lost power other than the clutch slipping?

"At certain times?" Theoretically it should slip when you apply torque, as in accellerating from a stop or on an incline?
