MC68HC05B32 EEPROM cleared problem

Hi,
 
We have been using the MC68HC05B32 devices for years without any problems (until recently).
 
Recently, some of our customers have reported that the contents of the onboard EEPROM have been wiped out. It appears that all of the bytes have changed to zeros.
 
What would cause the contents of the onboard EEPROM to suddenly change to zeros?
 
Thanks.
Don
