If the pressures equalize, a bad start capacitor will not always keep the compressor from starting.
There is typically a start switch. Potential or Current Switch. It has been a long time since I have done this work but it is a good idea to change the start switch with the caps.

Don't let the compressor cycle itself to death. Get some gauges on it and see if there has been a loss of charge.

Not sure if your condensing unit would have pressure switches on it but it could be cycling on a low pressure switch or inherent protection if the compressor motor is too hot. (could be other stuff too...)

Refrigerant cools the motor. Lack of refrigerant = hot motor.
