Sometimes the brakes are fine, then there is nothing(no pedal resistance, no stopping power), then they are back, strong and responsive. Could it be air in the line or master cylinder? I was going to bleed them but then they felt good.

Have you had any brake work done recently? Or has the Master Cylinder been Low enough for air to get into the system.

If so Bleed system, However sound like to me that the Master Cylinder is going.
