Why Script Stops After Some Game Rounds?

It Works, It Loads like 7 maps, then The Time (S.Value) Sets to 0, and does nothing, What Am I Doing wrong?

		local s = script.Stat
-------------------------------------------------
local f = workspace.FINISH.Fini


--------------inermission-------------------
t = 0
while true do
	t= 8
	repeat
		t= t-1
		s.Value = "Next Map Loading in "..t
		wait(1)
	until t == 0

game.Workspace.Lobby.DROPDOWN.Gate.CFrame = CFrame.new(95, 192.5, -1304)
game.Workspace.Lobby.DROPDOWN.Gate.Transparency = 1

-----------------------------
game.Workspace.Gravity = 20
------------- Maps------------------------
		local Maps = {'Yellow','Purple','Sphere','Cylinder','Spike','Rainbow','Lava','Ice','Eagle','YouTube','Sand','Umm','Carpet'}
local randomMap = math.random(1, #Maps)
for i,v in pairs(Maps) do
	if randomMap == i then
		local storage = game:GetService("ReplicatedStorage")
		local map = storage.Maps:WaitForChild(v):clone()
		map.Parent = workspace.MapPlaying
		
		if randomMap == 1 then
    f.Value = "Yellow Has Been Chosed"

elseif randomMap == 2 then
    f.Value = "Purple has Been Chosed"
elseif randomMap == 3 then
    f.Value = "Sphere Has Been Chosed"
		elseif randomMap == 4 then
			f.Value = "Cylinder Has Been Chosed"
		elseif randomMap == 5 then
			f.Value = "Spike Has Been Chosed"
			elseif randomMap == 6 then
			f.Value = "Rainbow Has Been Chosed"
elseif randomMap == 7 then
			f.Value = "Lava Has Been Chosed"
elseif randomMap == 8 then
			f.Value = "Ice Has Been Chosed"
elseif randomMap == 9 then
			f.Value = "Eagle Has Been Chosed"
elseif randomMap == 10 then
			f.Value = "YouTube Has Been Chosed"
elseif randomMap == 11 then
			f.Value = "Sand Has Been Chosed"
			elseif randomMap == 12 then
			f.Value = "Umm Has Been Chosed"
elseif randomMap == 13 then
			f.Value = "Carpet Has Been Chosed"
end
end
end
wait(1)
f.Value = ""

		
		t = 17
		repeat
			t = t-1
			s.Value = t.." Seconds Left To Complete DropDown"
		wait(1)
		until t == 0

target = CFrame.new(40, 162.06, 70)

    player.Character.UpperTorso.CFrame = target
    --add an offset of 5 for each character
end


				game.Workspace.Lobby.DROPDOWN.Gate.CFrame = CFrame.new(41, 159.5, 21.5)

end

s.Value = "Game Ended"
wait(5)

I think I know what it is. You do not have a while loop to loop the whole thing, so it stops.
