Windows 10: System reboots after about an hour or so of sleeping

Can someone please help identify the source of this issue? If I walk away from my computer for about an hour or so, it will restart on its own after it goes to sleep. I'm thinking it may have to do with a driver, from my research.It creates minidump files after each restart.DRIVER_POWER_STATE_FAILURE 9fA device object has been blocking an IRP for too long a timeAny solutions would be welcome.Thank you.Here is the contents of the latest .DMP file:************* Preparing the environment for Debugger Extensions Gallery repositories
