How come the backpack items don't reappear when the player respawns?

I am a beginner scripter and I have been working on this script. It is supposed to add more gear to the players backpack every time they level up, and that part works, but when they die none of the gear respawns. I tried solving it with the character:WaitForChild("Humanoid").Died:connect(function() in order reset the lev0 variable to false, but that didn't seem to work. The real script is larger, with 10 different functions for 11 levels, but I only included the lev0 function to make it easier to read. Please help me!

game.Players.PlayerAdded:connect(function(player)
wait(2)
local stats = player.leaderstats.Level.Value
local alive = true
local lev0 = false

	player.CharacterAdded:connect(function(character)
			alive = true
		character:WaitForChild("Humanoid").Died:connect(function()
			 alive = false			
			 lev0 = false
		end)
	end)


	while stats and alive == true do
		if stats >= 0 and lev0 == false then
			local flashlight = game.ServerStorage.Flashlight:Clone()
			flashlight.Parent = player.Backpack
			lev0 = true
		end
	end
end)
