Of course not. But God is Spirit and never dies. Jesus's human body "died" in the sense that we naturally think of death. He truly physically died. He went to the Paradise part of the underworld at that time and raised Himself from the grave. He never ceased being God. But I think we need to be very careful when we make statements like "God died." Particularly when it comes to 60s radicals :)
What scriptural reference do you have to that?
