He didn't die. He suffered brain damage, but managed to stay alive. And when he was connected to the Soul Translator after the incident, he had memories up to the incident. If you're referring how he doesn't remember anything at the very beginning of the story, then that was actually part of his part-time job before the incident. His memories were blocked so that he wouldn't ruin the project and wouldn't remember anything that happened during the dive.
