How can I reset a script after your character dies?

I'd like to know if there is a way to reset a script because I made an ability script that gives you an ability depending on which one you choose, but when you die, it only activates your previous ability. If there is a way to reset a script then I would like to know! If there is another way, here are two scripts (both of which are localscripts and I am not changing that):

local pow = game.Players.LocalPlayer:WaitForChild("PlayerGui"):WaitForChild("PowerGui2"):WaitForChild("Frame")
local ability = pow.Power

local plr = game.Players.LocalPlayer.Character
local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(inputObject, gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.Q and ability.Value == 1 then
            game.ReplicatedStorage.Speedparticle:Clone().Parent = game.Players.LocalPlayer.Character:FindFirstChild("UpperTorso")
            game.Players.LocalPlayer.Character:FindFirstChild("Humanoid").WalkSpeed = 40
            wait(10)
                game.Players.LocalPlayer.Character:FindFirstChild("UpperTorso").Speedparticle:Remove()
            game.Players.LocalPlayer.Character:FindFirstChild("Humanoid").WalkSpeed = 16
        end

local RS = game:GetService("ReplicatedStorage")

local remoteEvent = RS:WaitForChild("RemoteEvent")

UIS.InputBegan:Connect(function(inputObject, gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.Q and ability.Value ==2 then
        remoteEvent:FireServer() --Nothing passed to the server
						wait(0.5)
		for i, Child in pairs(plr:getChildren()) do
			if Child:IsA('Part') or Child:IsA('MeshPart') or Child:IsA('Accessory') then
				Child.Transparency = 0.5
			end
		end	
		plr:FindFirstChild("Head").face.Transparency = 0.5
		plr:FindFirstChild("HumanoidRootPart").Transparency = 1
		wait(9.5)
		for i, Child in pairs(plr:getChildren()) do
			if Child:IsA('Part') or Child:IsA('MeshPart') or Child:IsA('Accessory') then
				Child.Transparency = 0
			end
		end	
			plr:FindFirstChild("Head").face.Transparency = 0
		plr:FindFirstChild("HumanoidRootPart").Transparency = 1
    end
end)

UIS.InputBegan:connect(function(inputObject, gameProcessed)
	if inputObject.KeyCode == Enum.KeyCode.Q and ability.Value == 3 then
		game.Players.LocalPlayer:WaitForChild("PlayerGui"):WaitForChild("beserk").Value = true
		for i, tool in pairs(plr:getChildren()) do
			if tool:IsA('Tool') then
				for i, child in pairs(tool:getChildren()) do
					if child.Name == "Blade" then
						game.ReplicatedStorage.BeserkParticle:Clone().Parent = child
					elseif child.Name == "BeserkScript" then
						child.Disabled = false
					end
				end
			end
			end
			plr.Humanoid.WalkSpeed = 25
		wait(10)
		plr.Humanoid.WalkSpeed = 16
			for i, tool in pairs(plr:getChildren()) do
			if tool:IsA('Tool') then
				for i, child in pairs(tool:getChildren()) do
					if child.Name == "Blade" then
						for i, particle in pairs(child:getChildren()) do
							if particle:IsA('ParticleEmitter') then
								particle:Remove()
							end
						end
					end
				end
			end
		end
		game.Players.LocalPlayer:WaitForChild("PlayerGui"):WaitForChild("beserk").Value = false
		end
end)

local remoteEvent2 = RS.RemoteEvent2

UIS.InputBegan:connect(function(inputObject, gameProcessed)
	if inputObject.KeyCode == Enum.KeyCode.Q and ability.Value == 4 then
		remoteEvent2:FireServer()	
	end
end)
end)

The script below is the script that applies your choice

local pow = game.Players.LocalPlayer.PlayerGui.PowerGui2.Frame.Power
script.Parent.Select1.MouseButton1Click:Connect(function()
	local gui = game.Players.LocalPlayer.PlayerGui.PowerGui2.Frame
	gui.Select1.Text = "Selected"
	gui.Select2.Text = "Select"
	gui.Select3.Text = "Select"
	gui.Select4.Text = "Select"
	pow.Value = 1
end)

script.Parent.Select2.MouseButton1Click:Connect(function()
	local gui = game.Players.LocalPlayer.PlayerGui.PowerGui2.Frame
	gui.Select1.Text = "Select"
	gui.Select2.Text = "Selected"
	gui.Select3.Text = "Select"
	gui.Select4.Text = "Select"
	pow.Value = 2
end)

script.Parent.Select3.MouseButton1Click:Connect(function()
	local gui = game.Players.LocalPlayer.PlayerGui.PowerGui2.Frame
	gui.Select1.Text = "Select"
	gui.Select2.Text = "Select"
	gui.Select3.Text = "Selected"
	gui.Select4.Text = "Select"
	pow.Value = 3
end)

script.Parent.Select4.MouseButton1Click:Connect(function()
	local gui = game.Players.LocalPlayer.PlayerGui.PowerGui2.Frame
	gui.Select1.Text = "Select"
	gui.Select2.Text = "Select"
	gui.Select3.Text = "Select"
	gui.Select4.Text = "Selected"
	pow.Value = 4
end)
