My 1v1 script won't work completely?

I have a 1v1 script that works fine to a point, after a player has died once, it removes the other players tools and sets both players back to the correct position but that only works once, I would like it to work an infinite number of times, please help me by telling me what I am doing wrong. The following code is only the necessary parts, everything here is the main part, all the little parts work fine.

local function GameEnd(plrWon,plrLost,tied,forceStopped)
for i,v in next,CurrentGladiators do CurrentGladiators[i] = nil end
	if forceStopped then
	SetAnnouncer(tostring(plrWon).." has left the game")
	wait(6)
	SetPlayerImages()
	SetAnnouncer("No match")
	elseif plrWon and tied == false then
	SetAnnouncer(plrWon.Name.." has won over "..plrLost.Name)
	IncrementScore(plrWon,1)
	wait(6)
	SetPlayerImages()
	SetAnnouncer("No match")
	elseif tied == true then
	SetAnnouncer(plrWon.Name.." was tied with "..plrLost.Name)
	wait(6)
	SetPlayerImages()
	SetAnnouncer("No match")
	else
	SetAnnouncer("Time ran out")
		if plrWon and plrWon.Character then
		Teleport(plrWon,Return)
		end
		if plrLost and plrLost.Character then
		Teleport(plrLost,Return)
		end
	wait(6)
	SetPlayerImages()
	SetAnnouncer("No match")
	end
end

local function DeclareVictor(plrWon,plrLost)
--print(plrWon.Name.." won")
if plrWon == plr1 then
Plr1kills = Plr1kills + 1
wait(4)
Teleport(plrWon,Spawn1)
Teleport(plrLost,Spawn2)
else if plrWon == plr2 then
	Plr2kills = Plr2kills + 1

	Teleport(plrLost,Spawn1)
