No, post your code here.
1. You need a way to tell the MCU that you have switched off the power; as a result, 5V is slowly going down.
2. When 5V reaches at 4.5V, then make an arrangement to interrupt the MCU to save your counter value into the EEPROM.
3. At power up, the MCU will read the EPROM, and it update the counter.
