After clearing them all, I started the car and monitored, after about a minute of idling the first 5 codes returned but the last 3 did not, The car was not misbehaving in any way and was driving fine. I'm guessing the last 3 will return when it stalls next.

4212,4222, 4232, and 4242 indicate the first four glow plugs are dead, or the glow controller is dead. Or both. Replace all glow plugs and the controller.
40A1 is an alternator issue. Check alternator output etc.
4B90 (low rail on start), 4560 and 4590 are all indicating low rail pressure.
It could be an intermittent fuel flow regulator on the HPFP. But it could be a few other items also....
