I replaced the crank shaft position sensor before I made the video...HmmmmI'm guessing bad crankshaft position sensor. Had that on my '95 Eagle Vision back in Y2K. In my case, the tach would just drop to zero, the car would lurch, and it would come right back up and be OK. It did this every once in awhile for a couple of weeks, until it died completely on my way to work. Had to hitch the last 2 miles to work. Had a coworker take me to the car at lunch and it started right up. Drove it right to the mechanic and they replaced the crankshaft position sensor. End of issue.
