It definitely sounds to me like something is crashing - especially if the power light is on but the only way to wake the system is through a hard reboot.

Anything in /var/log/messages for power, kernel, panic, failure, etc.?

If it's actually suspending but having trouble waking up, you should at least see suspend messages in the log. This is from my Fedora laptop:
[root@xi00859-lx ~]# cat /var/log/messages | grep -i "suspend"
Mar  2 00:53:47 xi00859-lx ModemManager[903]: <info>  [sleep-monitor] system is about to suspend
Mar  2 00:53:48 xi00859-lx systemd[1]: Starting systemd-suspend.service - System Suspend...
Mar  2 00:53:48 xi00859-lx systemd-sleep[2023]: Entering sleep state 'suspend'...
Mar  2 00:53:48 xi00859-lx kernel: PM: suspend entry (deep)

Unless you disabled it during install or after, kdump should be enabled. You can check to see if there is anything in /var/crash/. If there is, then that should help you track it down.

Hope this helps some!
