Ecco The Dolphin: Defender of the Future (Dreamcast). North American Version.
In the Four Ways of Mystery level, normally when Ecco is swallowed by the giant eel the game goes to the game over screen and the player hits Start to go back to the last check point. However sometimes instead of going back to the start of the level the player will be respawned just as the scene plays of the giant eel eating Ecco. This goes in a constant loop (game over screen, hit Start, scene plays again) until the Dreamcast is reset or the player lets the count down on the game over screen hit zero.
