First check the battery connections are Clean and Shiny dirty connections wont let the electricity flow properly.

This could also be a starter motor issue. The 'Click' is the solenoid, (an electrically controlled switch), operating and sending power to the actual starter motor. The 'Clunk' is the starter motor engaging but not actually turning the engine over. These are all signs the starter motor might be starting to fail. Get a Good mechanic to look, and listen, to it.

Dependent upon the car maker, there are specific instructions on rectifying this problem. If your car is an vintage car (about 30 years or more), then the thermostat could be playing up (stuck), and needs replacing. Good luck!

I'd need to see the pressure when it's kicking off. If the pressure is on the edge, it can cause it to drop on cooler days where the low pressure switch shuts it down. How do you know what charge is in it? Did you evacuate and fill with a scale? You CANNOT judge charge based on pressure alone. Impossible
