GUI doesn't appear when NPC respawns?

So this is a local script within StarterGui. This script works fine until the NPC dies and respawns back again when I press e within the distance BobsChat doesn't appear. Output and Developer console say nothing.

Is there a way for this to work when the NPC spawns back? Please help!, Many thanks for reading

local NPCChat = {
    [game.Workspace:WaitForChild("Bob").Torso] = {
        distance = 3, 
        GUI = game.ReplicatedStorage.BobsChat
    }
}


local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

mouse.KeyDown:connect(function(key)
    if key == "e" then
        for NPC, properties in pairs(NPCChat) do
            if player.Character and (player.Character.Torso.Position - NPC.Position).magnitude <  properties.distance and not       player.PlayerGui:FindFirstChild(properties.GUI.Name) then
                properties.GUI:Clone().Parent = player:FindFirstChild("PlayerGui")

            end
        end
    end
end)
