Multiple codes suddenly appearing like that immediately point to an ECU failure. That said some could be old codes that weren't cleared so if possible get the car recovered to a garage so they can be cleared, then see if any re-appear (or try an OBD reader).
I had this happen years ago with a Ford F*cus, and it was caused by a solder joint breaking on the plug into the back of the dash cluster where the ECU was located, causing all manner of codes and sudden loss of throttle like you describe. A simple re-solder of the plug fixed it, but took months to locate!
