Intermittent faults can be so hard to find. I hope they have tested the battery and made sure the cables are clean tight and secure I would be looking for a voltage drop or bad electrical connection in the starting circuit/ignition switch and starter itself. When the car wont start I would get someone to crank the car and measure voltage across the battery, it should be 12.6 volts at rest, above 10 on cranking. With the car in neutral or park when the car won't start try putting a jumper wire from the battery (+) to the small terminal on the starter and see if the starter will crank over at normal speed. You need a good volt/ohm meter and wiring diagram to get to the source of the problem.
