If death is permanent...
... does being inanimate for two days and some hours really equal death if you're walking and talking forever afterwards?
If death is permanent, then resurrection is impossible, so in this sense you're begging the question.
Now, if someone died (medically dead) for two days and some hours, and sprang back to life, I would say that equals death during that time.
Getting down to cases, if we're talking about Jesus, and Jesus is God, I don't think the Christian position is that
all of God was dead during that time. Just the Jesus part. Except that Jesus isn't a part of God, he is God. He and the father are one. But Jesus was dead, but God the father was NOT dead. Because someone had to resurrect Jesus, and if God was dead, he couldn't resurrect himself. Anyway, I think there's some questions here, but largely they have to do with the incoherency of the trinity.
