I have had a similar issue with high octane gasoline (race gas). Not sure if it was due to a higher ethanol content evaporating in the system after sitting or what. But on normal pump gas it has never done it. Good luck.

Sounds like the processor is loosing its NVROM like a battery connection or battery power to the ECM, The processor flash is not sticking, can be a bad ECM.
What chip and interface is he using?
