Random cutting out, possibly Aircon issue?

I have a UK spec S80 T6. Ive done the transmission flush, and replaced the radiator after finding ATF in the coolant. The car now seems fine, but will cut out as if the ignition has been switched off, and does it without warning, usually when slowing down It has been known to do it at idle, too. It restarts straight away and runs normally. This can be exciting, to say the least, especially at junctions. If you're travelling at normal speeds, it will miss one beat, then keep going.
My inexpert suspicions are aimed at the aircon, as it used to hunt on startup if the aircon was switched on. It only does this if the aicon is on, so I'm assuming it's connected in some way. Any ideas, guys?
Many thanks for taking the time to read this,
Steve.

According to his post it's a T6.

Yes, 2.8 twin turbo. Just been out in it again, no aircon switched on, but still doing it. It feels electrical, as there's no warning, it's as if the ignition has been switched off.
