A couple days ago I was uploading fine. Yesterday I tried to upload some new code the wizard made and was getting sync error. Today I am able to upload this code I found while searching about 90% of the time without errors.
The code I generate syncs out at about the same place everytime and I notice that when it pause uploading that the screen on the ree fangel comes back on.

Optiboot was the only one that would work when I wasn't having trouble uploading a couple days ago. After loading the small code and crazy amount of rebooting the controller I finally got it to finish uploading. I ordered the plus board Saturday so hopefully it fixes my problem and its not the cable which I don't believe to be the case but you never know.
