Every night before I go to bed, I put my Mac Pro into a sleep state. When I wake up in the morning the power light is blinking rapidly and the Mac Pro will not wake up. I have to push the power button, hold it down until the Mac shuts off.

My guess is you have a Early 2008 3,1 only because lately it seems so many do.
Had you tried Apple Hardware Test, hopefully (TTP 6 rarely does), and reset smc.
Do you have 3rd party controllers and devices that don't support sleep?
Also, try normal troubleshooting - I'd start with a fresh install and update and test with this system (clone as you go if needed) and only gradually add back in.Troubleshooting: My computer won't turn on

If you test a Mac Pro (Mid 2010 and later) with Apple Hardware Test (AHT), you might encounter an alert indicating that the computer does not pass the reading of the following sensor:

The flashing LED indicates a hardware fault, usually bad RAM but sometimes the logic board. "Tech Tool Pro" is worthless. The Apple Hardware Test isn't much better, but you could try it.
