Car stalls when turning sharply left or right and stopping; and hitting curb cut. Can be immediately restarted, I suspect bad ground connection somewhere but do not know where to look. No codes are entered when this happens.

This sounds like you have a wiring harness that is shorting out. With the engine running, open the hood and grasp any visible wiring harnesses and move them around to see if you can get the engine to act up. Also, it could be a vacuum leak (test when the engine is cold) or a dirty throttle bore actuator. These guides can help us fix it:
