How do you pause a script without making it start over again?

little example on how you can stop and start a script without disabling it.

--// this creates a bool Value in the workspace so you can see it working, Just look for a Go Bool Value in your workspace!
local DoGo = (function()
    local D = workspace:FindFirstChild("Go")
    if(D == nil) then
        D = Instance.new("BoolValue",workspace)
        D.Name = "Go"
    end
    return D
end)()

-- Simple timers to show how long we're either running for or waiting for... These are not needed to do this. Its just a fancy way to show it working!.
-- Grab our starting tick via tick()
local StartTime = tick()
local WaitTime = tick()

-- main Loop
while true do
    if(DoGo.Value == true) then -- if our Go value is true then start everything
        local NowTime = math.floor(tick() - StartTime + 0.5)
        print("Woo!, We're been computing since [",NowTime,"] Secs!")
        WaitTime = tick()
    else -- our go value is false lets wait!...
        local MyWaitTime = math.floor(tick() - WaitTime +0.5)
        StartTime = tick()
        print("Waiting ", MyWaitTime , "Secs!")
    end
    wait()
end

hope this helps! :)

Just do event:Wait() and the event is anything you want like a bindable event or something
