Those were the exact symptoms I had a couple of weeks ago. It only did that once each trip for a few days, never showing any codes. Then it cut out, the DSC and Check Engine lights came on, and it ran with hugely reduced power. Replaced the crank position sensor and it still was in limp home mode with the DSC light on and minimal power. Limped to the local shop, had them use their computer to clear all codes and adaptations that my scanner couldn't do, and it started and has run perfectly since then.
