Fixes I've heard of for this -

Bad BCM,
Loose power wire going to fuse box,

And one time heard of a guy who found out that one of his o2 sensor wires was shorting out due to the insulation scraping off, causing your problem.

That last one is kind of a long shot, I know.

Did you get an ecm or bcm? Just wondering cause they aren't the same thing.

And this may sound weird but I was just reading about some people who fixed this problem simply by disconnecting their battery for ten minutes, although I cannot verify it myself.
