Check your ECM connector and add some dilectric grease when you unplug it.

 

Wanted to update. The problem seems to have been simply a bad ground. I did have a little corrosion on my negative battery terminal. After having the battery load tested, it tested good, I cleaned up the terminal, cleaned all the ground cables and the strap at whitch the ground cables mount, added dyellectric grease and she has been good to go so far.
