Hello,

The crankshaft position sensor code likely sets as a result of the stall itself.

Testing needs to go back to basics. When the problem occurs, check for fuel pressure and delivery to the engine. Spark present at the spark plugs. The proper amount of air coming into the engine, and the proper exhaust flow.

One or more of those elements will be missing. Then, troubleshoot down that path. Note: guessing is a bad idea; follow the testing to find the answers.
