2019 Suburban Stabilitrak error

here's an issue with my car. every once in a while the Stabilitrak will fault and reduce the power steering. When that happens, any stress on the steering will cut power to the a/c fan. If it gets stressed too hard (i.e., turn fast when car is below 5mph or stopped) the engine shuts off. When I restart, everything is fine. no check engine light or other errors showing.
