Is there a signal being driven into the amp? Some amps won't continue to oscillate without signal.
There's nothing there that would produce a negative rail on the output. What changed from when the amp was heating the 100 ohm resistor?

With the 100 ohm, you had full negative rail on the resistor. Are you saying that that negative rail voltage is gone?
Yes.
Now when I power it up, it starts to draw current 5 seconds after power up. When this happens the amp starts to squeal.
