That's the ID and firmware version message displayed if you hold Fire while inserting a battery.
My first thought is that your battery is either intermittently making/losing contact (something loose or loose fitting in the battery sled?) or it's sagging so much under load that the mod shuts of and restarts as the battery recovers (just takes a fraction of a second).
Those would be "best case" scenarios.
What make and condition is your battery?
Have you tried others?
