Vapor Pressure
Chris, this is a popular theory, though it brings up unfortunate implications. (See posts #261 and #602). Fuel Exhaustion is "ostensibly" ruled out, Fuel Starvation has been obliquely addressed, Engine Response is on the Record, Fuel contamination has gotten little buzz. (Notwithstanding the public disclosure of Fuel "testing" absent conclusion as to causation or even postulate). The Fuel "tests" were left unaddressed, and the public does what it always does, "assume" that means the Fuel is cleared. Not so. Everything points to Fuel issues, storage, transit, pumping, temperature, Engine response, etc. even quality. My fear is that the longer the investigative authority takes to update, the more it will overemphasize the ultimate outcome of the investigation. (I hope "Sinoadditve" does not become a new word in the Dictionary, for many reasons.)
