What is your iPhoto version? I assume you have a recent version, iPhoto '09 or later?
Probably your iPhoto library got corrupted and needs repairing.
Make a back up copy of your iPhoto library and try rebuild the library:
- Hold down the command and option/alt keys and double click the iPhoto icon to lauch iPhoto.
- You will see the "First Aid" panel with repair and rebuild options. Choose "Rebuild Database".
