I can "out-scary" this, as the same thing happened to me on a couple of occasions (so yes, it WILL). Interestingly, both times in Alabama. My experience the first time was similar to yours- I coasted to stop, then turned the ignition off and back on and drove away. The second time, it happened while I was driving through the I-10 tunnel in Mobile, where coasting to a stop on the side of the road didn't seem like a viable option. I turned the ignition key to the off position while going about 50 m.p.h.(!) then back on and everything was good. After about a year of seemingly random and intermittent problems with the van, I ultimately discovered that one of the FI wires had been damaged due to compression by the AC motor and was creating a short. Since that wire was repaired, the "sorta scary event" never recurred, so I assume that the short circuit was the culprit. You might want to check for the possibility of similar electrical issues in your place.

Good luck,
