Check the alternator pig tail. The wires are know to become brittle and break. It may be temporary loosing the connection to the alternator and stalling the car. If it happened while you were turning, you changed the forces on the car which could have shifted the wires just enough.
When I changed mine, they felt secured when the plug was still in the car but as soon as I clipped it and pulled the connector, the middle wire literally fell out.
