Re: Turning left lose engine power.
I had the exact same problem with a very different car some years ago. I was driving a 1984 Rover SD1 that would stall on tight right-hand turns. Turned out the wiring to the condenser (I think) was close to the engine block and had melted the insulation. On a tight right hander the g-force would cause the bare wire to earth itself on the engine block, earthing the ignition system and killing the engine.
I know your car has electronic ignition but sounds like it could be broadly similar - some wiring or connector is loose and either losing contact or making contact with something it shouldn't on a bend due to g-forces.
