Resetting Garmin 610

I have had my Garmin 610 since Xmas. In the last 2 weeks it would go completely dead within the first 1/2 mile of a run. It would just shut down. I updated with the latest firmware. It shows 100% (fully charged) before each run. I also did a 'restore defaults'. The issue still persisted. So, I reached out to Garmin via email. I received the following response, and am happy to report it resolved the issue. I’m posting in case you experience a similar issue:

Thank you for contacting Garmin International.
 
I am sorry about this trouble you are having with your Forerunner 610. You mentioned doing a 'restore to defaults', I would suggest trying a master reset. There are a few instances in which a master reset can be performed on the Forerunner 610, 210, or 110, such as:
 

• Not functioning properly
• Needing to be restored to factory default settings
• Not receiving a satellite signal*
• To bring up language selection prompt if incorrect language text is showing
• Unable to pair up accessories, such as the heart rate monitor or foot pod

By doing this reset, all user information, workout history, and satellite data may be erased. Workouts can be backed up to training programs like Garmin Connect. Also, refer to FAQ article "How can I back up my personal settings and profiles on my Forerunner 110 or 210?" if using the Forerunner 210 or 110.
 
To perform the master reset:
 
1. Start with the device powered off
2. Press and hold Start/Stop and Lap/Reset
3. Press and hold Light (three buttons should now be pressed in)
4. After first beep, release Start/Stop
5. After second beep, release Lap/Reset
6. Release Light
 
The reset on the Forerunner is successful if the device finishes powering up and goes to the setup wizard. Try the steps again if the setup wizard does not appear.
 
If the reset fails to correct this the Forerunner would need to be sent to Garmin for exchange.
