Thank you both for taking the time to help.

Did you uninstall a bunch of stuff on the 14th? Like something related to Visual C?

On the 13th I downloaded the demo of 3DMark to get an idea of benching to as well get an idea/handle of  overclocking with XOC 6.0.9. I ran TimeSpy five times than when done uninstalled it. I also was using Arkham Knight to bench with the in game bench before 3DMark as it is the most graphically intensive game I own besides Watch_Dogs (that doesn't have a bench) through UPlay at the moment. After all the benching till the end of the day was went back to AK to just play it for 30-40 minutes till turning off the PC for the day with no problems. Not till the following day as stated.

Uninstall the game completely. If you have more than one SSD/hard drive change the default install of the game (or all Steam games) to another SSD/HD and then see if that works.

"Uninstall the game completely." I did this today.. explain completely? I going to want the saves of my progression. I would be able to move it back to the system drive (Seagate Hybrid Drive 1TB SSHD) after as the 2nd drive (Seagate Barracuda 1TB HDD) is right now just for backing up system drive?
 
Edit to both: After when I uninstall stuff I also go in to CCleaner to delete the registry it picks up as an issue and most all the time is something that has been uninstalled. 

How do I go about repairing Visual C++ in Win10 if that is the cause?
I have gotten in touch with WB Games Support and they asked me send them the information about the current installation of DirectX on my computer with DxDiag utility. 
I have tried other games and the ones I ran worked without problems. Arkham Knight is one of my favorite games on my computer and have 65 hours invested since May 11th this year.
I looked at Control Panel\All Control Panel Items\Security and Maintenance\Reliability Monitor and found this for every time AK crashed

Will update here if anything changes.

No, i didn't just clicked uninstall in the Steam UI.
Yes, I did see my save files in my documents folder. Just didn't know if that was apart of "Uninstall the game completely"?
 

So I should delete C:\Program Files (x86)\Steam\steamapps\common\Batman Arkham Knight but I can leave C:\Users\Owner\Documents\WB Games\Batman Arkham Knight alone and I see GFXSettings.BatmanArkhamKnight.xml is in this folder... maybe delete that too and only keep SaveData? And cross my fingers. 
 
Edit: Okay going see if it do the trick.
 
Edit2: That did it ran the game for over 2 hours on problems.
 
Now I have a to defrag the system drive of sum 3,430 fragments. Joy, there goes half a day.
 

Can you believe it this happen to me again!
I resonantly installed a case fan and was benching so one of the things I used to bench with was Arkham Knight.
The exact same thing happened and had to do the exact same thing above to fix it.
I will never use the performance set in AK ever again. It must be the cause of the above error crash.
