This sounds so much like my 2000 Chevy Impala stalling problem. No warning lights, no codes, stalling for no reason, and able to restart and drive as if there was nothing wrong.
My problem was found to be caused by the Crankshaft Position Sensor.
I read that you have already changed the sensor, so all I can suggest is that you remove the good sensor and make sure the grooves in it are clean of debris (magnetic particles that build up during driving). Also,
I have read that there was a time when a bad batch of these sensors were put in service.
There is a max. Resistance test for this sensor, but I don't have the numbers or the procedure for it, and if it happens as a heatsoaking problem, it'll need to be heated for the test.
