I have ran into times it has taken 45 min to restart
I ran some searches and was able to kill the ram process but I would like a better long term solution

I'd suggest backing up your data and performing a clean install to get rod of whatever corruption might be going on to cause this. If that doesnt fix it then check hard drive health to make sure that the drive hasnt slowed down as for data is written to drive before shutdown.
