Thanks Enigma.
I was able to fix my parasitic draw issue, or at least it's gone for now.
I remembered I was having problems with my ignition key switch a while back where the key was sticking and wouldn't turn easily. I decided to spray electronics cleaner into the key switch and worked the key in and out cleaning debris with a cloth. The parasitic draw stopped immediately.
Similar to the tailgate connector corrosion causing the PCM to not go into sleep mode, the ignition key switch was doing the same.
I'm symptom free for 5 days.
