I recently posted about the possibility of cassette replacement, and had some great tips, but my mechanic repaired my 9k by replacing crank sensor and it obviously didn't remedy the issue. The car lost all power again last night. sitting at a red light and suddenly, without warning, complete shut down. no electrical, no nothing. I fiddled with the battery cable and lights came back, but it took a minute to start. not sure of the exact nature/location of the problem. any ideas? thanks.
