You said the fault light was flashing. If so, the controller did not lose the program. If it had lost the program the light would have been solid red.
The controller had a fault, but because the program was re-downloaded, the specific fault code has been lost. So we don't know what the fault actually was. So this very possibly could reoccur.
In desperation, if this scenario ever occurs again, turn the keyswitch to Run, then Program, then Run. This will clear the fault and the controller will try to go back in to run mode. It might just fault again, but possibly if that fault condition does not still exist you might be able to get up and running. On most controllers doing this will wipe out the fault code on other newer 5/05 controllers they will keep the fault code stored so you can find out what the fault was.
The optional EEPROM can be configured to reload the program automatically on a power cycle. It actually has three options.
1. Reload on every power cycle.
2. Reload only if the program is missing/corrupt
3. Never reload automatically. Only will reload if the user via RSLogix software triggers the reload.
