Lots of things could cause good days and bad if it is skipping steps. Heat, resistance of mechanical components, lack of lubricant, dirty slides, ways, dull cutters, ect. Do us a favor and tune your motors down a little and see if it fixes it. Lower the accel. and vel. by 10% and let us know how it does.
The spindle issue sounds like it may be noise to me. If it is running the same code and nothing has changed except sometimes it doesn't start as it should noise is the only thing I can think of that would make it random. Ferrite chokes and/or cable shielding may help this.
