It stalls only when turning or driving around corners?
Have you checked the positive battery cable itself and the motor mounts? The terminals can be good but the cable may be stretched. Additionally bad motor mounts may pull at the cable when you accelerate the engine into or out of the turn.

Another issue may be fuel sock in the tank may shift when you go around turn.

Also, check the wiring harness going from the PCM to the sensors. A frayed wire or loose pins or loose connection or corroded ground wire to the body.
