Driving the car slowly through the neighborhood and engine loses power, Message screen says "Engine Fail Safe Mode" then reduces car to idle mode so you can't even pull a slight grade. I shut the engine down, locked and unlocked car, restarted and it ran fine with no messages or faults left behind. Does anybody know what caused this? Planning a 400 mile trip next week but not sure I should take the Aston.

Thanks for any help or advice.

I'd plug in an OBD reader and see if any codes got stored.
