Why does my LocalScript only fire once?

I have this in a LocalScript

humanoid.Died:connect(function(Died)
	for i, v in pairs(game.Players:GetChildren()) do
		if v.TeamColor == BrickColor.new('Bright red') and v.Character.Humanoid.Health == 0 then
    		print('Red has died')	
		event:FireServer()
		end
	end
end)

However if I reset my character again while still meeting the conditions, nothing happens. If I check and uncheck the Disabled property on the script and reset, it works....why is it doing this?

im confused. if its a local script you can go and do game.Players.LocalPlayer.Character

game.Players.LocalPlayer.Character.Humanoid.Died:connect(function(Died)
        if game.Players.LocalPlayer.TeamColor == BrickColor.new('Bright red') and game.Players.LocalPlayer.Character.Humanoid.Health == 0 then
        	print('Red has died')   
        	event:FireServer()
        end
end)
