2013 Scion FRS; NA tuned and in process of setting up Flex Fuel.

I was going through some tuning revisions with Zach from CSG and needed to fill up to a full tank of gas. After filling up, I got on the highway and did a pull for datalogging successfully with no anomalies. Shortly after completing the pull, no more than 5 minutes. The car outright dies. After pulling over and checking for anything catastrophic like a window in the block. I tried starting the car. Never kicked over, just kept spinning the engine.

Any suggestions or ideas?

Bubba says you got some "bad gas".
