If player dies the script doesn't run?

When a player dies in game, the script no longer works. Before the player dies everything seems fine but when they die, it wont work. There's no output either. I looked through my script and found nothing. Someone help.

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local remote = game.ReplicatedStorage.TeleRemote
local remoted = game.ReplicatedStorage.TeleRemoteD
local mtarget
local mtarget2
local down
local partic
local f4
local attach0
local attach1
beam = game.ReplicatedStorage.TeleBeam
local cool = true
game.StarterPack.LocalScript.Value.Name = player.Name


mouse.Button2Down :connect(function()
    --if game.ReplicatedStorage.Mana.Value < 20 then return end 
    if cool == true then
        remote:FireServer()
        mtarget2 = game.Workspace.Tele
        attach0 = mtarget2.TeleAttachment
        attach1 = player.Character.RightHand.RightGripAttachment
        down = true
        mtarget2.ParticleEmitter.Enabled = true
        beam.Attachment0 = attach0
        beam.Attachment1 = attach1
        beam.Parent = attach1.Parent
    end
end)

mouse.Move:Connect(function()   
    if down == true then 
        local posX,posY,posZ = mouse.Hit.X,mouse.Hit.Y,mouse.Hit.Z
        mtarget2.CFrame = CFrame.new(posX,posY,posZ)
    end
end)

mouse.Button2Up:connect(function()
    if cool == true then
        if down == true then
        game.ReplicatedStorage.Mana.Value = game.ReplicatedStorage.Mana.Value - 0
        cool = false
        remoted:FireServer()
        f4 = game.ReplicatedStorage.ParticleEmitter2:Clone()
        mtarget = player.Character.HumanoidRootPart
        local posX,posY,posZ = mouse.Hit.X,mouse.Hit.Y,mouse.Hit.Z
        mtarget.CFrame = CFrame.new(posX,posY,posZ) + Vector3.new(0,3,0)
        down = false
        mtarget2.ParticleEmitter.Enabled = false
        beam.Parent = game.ReplicatedStorage
        cool = true
        end
    end
end)
