Ford F-150 (2004-2008) :: FX4 - Continuous Chiming From Under The Dash When Driving

I have an 04 F150 FX4, I was driving it and starting continuously chiming from under the dash. The chime was the same as the low fuel light but was repetitive. I assumed it to be a warning and I started watching my gauges to find my voltage dropping. So I rushed it back home and couple miles out the dash, radio, accessories, etc power went out in what I assume to be a power save mode.

I get it back home and turn it off. I go to attempt to restart it and no crank. I think ok maybe my alternator went out, so I jumped the battery off my car and still no power. When I mean no power, truck is getting proper voltage but when I turn the key to attempt to start there are still no cranking, no dash/radio/windows. I noticed two things: ABS light blinks different codes but nothing consistent, and secondly the anti-theft light when turning to start blinks rapidly.

I believe this is unrelated to the problem, but my clock spring broke few months back. Since the anti-theft light blinks rapidly i'm assuming the PATS system is not communicating with the key. I only have one key for the truck. I check every fuse, swapped relays in fuse panel on passenger side and everything looked good. I called a locksmith who can cut and program keys and he called his technical support and said he doesn't believe that two new programmed keys will solve the problem.
