Sounds like your ECM (engine control module) got confused and the computer program wasn't robust enough to reset without turning off the engine. Strange things can happen when the ECM gets bad info. I had a 2000 that had one of it's 7 ground wires go inconsistent. My scan gauge wouldn't identify it, but a garages big diagnostic tool determined the engine thought it was at 20mph in 2nd gear when I started out from a stop. Made from so pretty erratic cockpit readings, and bumpy starts. When it first started I could stop the engine and restart and it would go away for months. Later (several years) it got too consistent to ignore.
Shutting down and restarting reset the ECM. If it doesn't happen again I would ignore it.
