BBB reboot to Angstrom while running custom build OS

I currently have a Custom build OS that I load to BBB via UART serial connection. After about 1-3 Min the Beagle will reboot and load Angstrom. The OS is still in development, but is stable, and is frequently downloaded.

powered: USB connected to computer
Serial: tty via USB converter on the J1 serial connection

downloading OS and booting BBB with bootm command

OS boots and I can utilize the shell for a shot time 1-3 Min before the Beagle reboots to Angstrom

Any help is greatly needed and appreciated
