What do you mean it restated? Is it a manual?
If so, yes I have had some strange similar experiences
In all my driving a few times it has happened to me. I literally stalled the engine pulling out from a stop, or oh so close to stalling. A few times I would catch it and push the clutch in. The dash lights came on the chech emgine light was on, as if it was stalled, but I caught myself and kept the engine running.
Sounds like you had a similar thing. No issues no ill effects. I stopped turned the key off and restarted the vehicle all was fine again.
Seems like a quirk in the computer system when you drop to an very low rpm all almost stall out the engine.
Also I don't know if you noticed. But I did before. The dash lights when on the gauges where all at zero, tach, speedo, gas gauge, yet the engine stayes running.
