This is Steinitz vs Bardeleben. It isn't exactly what you describe, but Bardeleben walked out basically letting his time run out. Reports on this are sketchy I believe... some reports have it that he left a note saying good game... but regardless... it is an amazing combination and Bardeleben was apparently a bad sport about the loss.
One of the early 20th century greats (Alekhine or Capablanca I think) playing a relative unknown. The the game ended with a knight and queen advance on the king's side, I believe the winning player was white. It was the game where the losing player simply got up and left without resigning with somelike a 10 move mate or disastereous loss of material on the table. This is all very vague, but I would really like to find that game again.
