Mondeo aircon problem

Mk III Mondeo
I have found several tales across the web of exactly the same problem I have - the aircon works fine for a few minutes, then all cooling fails. If the outside ambient is high, it sometimes
doesn't work at all.
Others report that simple re-gassing has no effect, similarly the last time I had mine checked was a cold day, they claimed all was well, but hadn't run it long enough to get it to fail.
Has anybody found the solution?

Step 1: when the A/C fails is the compressor engaged or not?

If it isn't too obvious a question, how do I tell?

I suspect if you don't already know the answer to the question, you probably should take the car to an A/C specialist.
Open the hood. Have someone start the car and engage the A/C while you observe the A/C compressor pulley. When the A/C compressor clutch engages you should hear a click. All of the A/C clutches I am familar with have a central hub that is connected to the actual compressor. The outer pulley (where the belt runs) is either engaged or disengaged from the hub via a magnetic clutch. When the clutch is engaged, the central hub spins with the pulley. When the clutch is not engaged, the hub is stationary. If the hub is stationary, the compressor is not running and you won't have any A/C.
