Unable to resume dead coroutine? {Figured out a fix - Solved}

I'm going to simplify my script here:

endroutine = false

func = coroutine.wrap(function()
    while true do
        wait()
        --do some stuff that has to happen with other stuff unless stuff is done
        if endroutine then return end
    end
end)

func2 = coroutine.wrap(function()
    while true do
        wait()
        --do other stuff that has to happen with other other stuff
    end
end)

function dostuff()
    --do stuff
    endroutine = true
    --do more stuff
    endroutine = false
    func()
end

func()
func2()
wait(10)
dostuff()

My issue is that when func() is called in dostuff(), I get an error along the lines of: "Unable to resume dead coroutine."

I tried the following:

endroutine = false

function func()
    while true do
        wait()
        --do some stuff that has to happen with other stuff unless stuff is done
        if endroutine then return end
    end
end

func2 = coroutine.wrap(function()
    while true do
        wait()
        --do other stuff that has to happen with other other stuff
    end
end)

function dostuff()
    --do stuff
    endroutine = true
    --do more stuff
    endroutine = false
    coroutine.wrap(func())
end

coroutine.wrap(func())
func2()
wait(10)
dostuff()

For some reason, the above code makes it so func2() never even runs in the first place, which is a problem since I need func() and func2() to run at the same time.

Simply put: Is there a way I can get both func() and func2() to run at the same time, and after func() has ended via "return end", be able to start it again from it's call in dostuff()?

Preferably without a lot of new lines of code; I like to try and keep my code as compact as possible.

It should be noted that in the actual script, dostuff() is called via a MouseClick event, not directly in the script.
