I have had this same issue with the same fuse blowing after my trailer brake plug was wired incorrectly for a few minutes. Now, even though it is wired correctly, the fuse will just randomly blow and cause all the exact problems that the OP described. Another thing is that the "R" for Reverse lights up every time I push the brake pedal when the trailer is plugged into the truck. I believe the incorrect wiring may have fried something inside the controller and causes a backfeed of voltage that blows the fuse over time

Hey guys thanks for all your help!!! I actually just figured it out!

Ok it's kind of dumb, but I will post for the sake of other people...

Before this started, I remembered working on my stereo. I used to have a backup camera installed, so I previously tapped the wire in the drivers side kick panel, and ran it to the head unit (aftermarket). So I tore apart the stereo, to find that the wire that taps the reverse lights for the backup camera, was just floating around. It was also stripped on the end from coming out of the connector. So this was grounded. Fixed the wire, and boom, no blown fuses.

Now I would have noticed my camera wasn't working and that would have led me to this conclusion faster, but I hadn't had a back up camera for months!

Long story short, the wire I tapped came loose and was creating a ground. Stupid, but oh well, happy now.

Thank you to everyone who helped me out, especially nd4spdbh. You guys rock, glad I got this taken care of!

I know it's been years, but here in 2020 you may have just saved me hours of brain racking and frustration. My backup camera stopped working the other night, then the P0705 issue started. I'm hoping my reverse light wire is grounding out. I'll post my findings. Thank you.

It was my backup camera grounding out! You saved me hours and probably thousands of $$$. Can't thank you enough.
