I am having the same issue. A while back the car would stall randomly for no reason. Opened up the fuel pump relay and found several cold solder joints. I re-soldered them and the problem almost went away. Every now and then the car will cut off but now only on hard right turns just like the OP.
In my case the KLIMA relay for the AC has been bypassed so I wonder if the computer is not getting a signal to increase the idle.
