Running Hassio on Rock64 Needs reboot to re-start

I installed Hassio using the documentation found on github site ( Everything installed with out a problem and the application runs good for awhile then it appears like it goes to sleep and the only way i can wake it up (commands issued in terminal don’t even work) is by rebooting the Rock64 with power reset. Any Ideas of what it could be or point me in the right direction would be appreciated.
