Burned up 5v Regulator

Kind of an odd issue. I have been running a DIYPNP in my supercharged Miata for about 4 years. Many trouble free miles.
However, last week I went to start the car and it ran then died after 4 seconds. After doing some diagnosis, I ended up pulling the computer to find that the 5v power regulator LM7805C had burned up.
Not sure why exactly that would have happened. Is there some common wiring mistake that shows up 4 years later? Any ideas would be greatly appropriated. Thanks
