Problem with my round script?

No errors, but it shows who won for about 0.1 seconds and then goes back to the "Round, please wait". What did I do wrong?

Award = 10
Award2 = 5
local gui = game.Workspace.Part1.v.z

game.Players.PlayerAdded:connect(function(plr)
	local leaderstats = Instance.new("IntValue")
	leaderstats.Name = "leaderstats"
	
	local points = Instance.new("IntValue")
	points.Name = "Points"
	
	points.Parent = leaderstats
	leaderstats.Parent = plr
end)

function Fight()
	for _, player in pairs(game.Players:GetPlayers()) do
		if player and player.Character then
			local humanoid = player.Character:WaitForChild("Humanoid")
			humanoid.MaxHealth = 10000
			humanoid.Health = 10000
		end
	end
	for i = 15, 0, -1 do
		if i <= 9 then
			gui.Text = "Intermission (0:0"..i..")"
		else
			gui.Text = "Intermission (0:"..i..")"
		end
		wait(1)
	end
	gui.Text = "Now choosing duelers."
	wait(5)
	
	local plrs = game.Players:GetPlayers()
	local p1 = plrs [math.random(1, #plrs)]
	local p2 = plrs [math.random(1, #plrs)]
	ended = false
	repeat p2 = plrs[math.random(1, #plrs)] until p2 ~= p1
	
	gui.Text = p1.Name.. " and " ..p2.Name.. " have been chosen to duel."
	wait(3)
	
	p1.Character.Torso.CFrame = CFrame.new(147.5, 14.6, 15) 
	p2.Character.Torso.CFrame = CFrame.new(147.5, 14.6, -59)
	
	local sword1 = game.ServerStorage.Sword1:Clone()
	sword1.Parent = p1.Backpack
	
	local sword2 = game.ServerStorage.Sword2:Clone()
	sword2.Parent = p2.Backpack
	
	for i = 3, 0, -1 do
		gui.Text = "Starting in " ..i
		p1.Character.Humanoid.WalkSpeed = 0
		
		p2.Character.Humanoid.WalkSpeed = 0
		wait(1)
	end

	p1.Character.Humanoid.MaxHealth = 100
	p1.Character.Humanoid.Health = 100
	p1.Character.Humanoid.WalkSpeed = 16
	
	p2.Character.Humanoid.MaxHealth = 100
	p2.Character.Humanoid.Health = 100
	p2.Character.Humanoid.WalkSpeed = 16
	
	for i = 30, 0, -1 do
		gui.Text = "Round, please wait (0:"..i..")"
		if i <= 9 then
			gui.Text = "Round, please wait (0:0"..i..")"
		end
		wait(1)
		p1.Character.Humanoid.Died:connect(function()
			p2.leaderstats.Points.Value = p2.leaderstats.Points.Value + Award
			gui.Text = p2.Name.." has won."
			game:GetService("PointsService"):AwardPoints(p2.userId,150)
			wait(3)
			ended = true
		end)
		if ended == true then
			break
		end
		p2.Character.Humanoid.Died:connect(function()
			p1.leaderstats.Points.Value = p1.leaderstats.Points.Value + Award
			gui.Text = p1.Name.." has won."
			game:GetService("PointsService"):AwardPoints(p1.userId,150)
			wait(3)
			ended = true
		end)
		if ended == true then
			break
		end
	end
	p1.Character.Torso.CFrame = CFrame.new(190.2, 3.8, -25.6) 
	p1.Character.Humanoid:UnequipTools()
	p1.Backpack:ClearAllChildren()
	
	p2.Character.Torso.CFrame = CFrame.new(184.2, 3.8, -25.6)
	p2.Character.Humanoid:UnequipTools()
	p2.Backpack:ClearAllChildren()
end

while true do
	if game.Players.NumPlayers > 1 then
		wait(1)
		Fight()
	elseif game.Players.NumPlayers == 1 then
		gui.Text = "Waiting for 2 or more players."
	end
	wait()
end

Function connected by events dont make delays in the script. Try doing this:

if player.Humanoid.Health = 0 then
	--Code
end
