Hello dear. A good mechanic, always begins from the simplest to the most complex. If you talk that your car loses power and stops, you must have a problem, in your fuel admission and circuit, I mean that it must be dirty, so you should start by making a tune, including injectors lipiege. If you have done it, and the problem persists, I recommend scaar your vehicle, to rule out possibility, that some sensor is producing an anomaly in the operation of your engine.
Regarding the clutch question, I do not understand what you mean by graduating the clutch. Your clutch is not hydrauyl, yes, not hydraulic drive, so if it is failing etc, specifies more on the subject.
