This script stops working when the player dies, why?

I'm making a script when you press some keys it increases some values, but it stops working when the player dies, here's the script

local player = script.Parent.Parent
local name = player.Name
local human1 = workspace:WaitForChild(name)
local human = human1:WaitForChild("Humanoid")
print(name)
local coolE = false
local keyheld = false
local coolQ = false

local stats = game.ReplicatedStorage:WaitForChild("stats"..name)
local power = stats:WaitForChild("power")
local ki = stats:WaitForChild("ki")


local function onKeyPress(inputObject, gameProcessedEvent)
    if inputObject.KeyCode == Enum.KeyCode.E and coolE == false then
        coolE = true
        power.Value = power.Value + 5
        local animation = Instance.new("Animation")
        animation.AnimationId = "http//roblox.com/?id=1312116274"
        local animTrack = human:LoadAnimation(animation)
        animTrack:Play()
        print("more power")
        wait(0.5)
        animTrack:Stop()
        coolE = false


    elseif inputObject.KeyCode == Enum.KeyCode.Q and coolE == false then
        local animation = Instance.new("Animation")
        coolE = true
        animation.AnimationId = "http//roblox.com/?id=01335430799"
        local animTrack = human:LoadAnimation(animation)
        ki.Value = ki.Value + 5
        print("more ki")
        animTrack:play()
        wait(0.4)
        coolE = false
        animTrack:stop()



        end
        end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

When i die the output shows it: 23:13:21.798 - LoadAnimation requires the Humanoid object (VoltronInhe.Humanoid) to be a descendant of the game object
