After changing the fuel filter and putting in a small bottle of Kleen-flo gas line anti-freeze, I half filled the gas tank with 91 octane ethanol free gas. The change was immediate. No more stalling or sputtering.
I subsequently replaced the o-rings on the throttle body and while doing that I broke the PCV Crank Case Vent Hose from Oil Trap to Throttle Body right at the check valve. It was very brittle. Now replacing that was really fun. I will do a write up on how I did that as it may help others.
Now I'm driving the car and waiting for the gas level to go down to less than 1/8th. We'll see if it really was just bad gas.
Thanks for all the helpful suggestions.
