Well, before starting to "shotgun" parts at it, it would probably be a good idea to get a scanner on it, & see what it has to say. It doesn't sound like you've changed anything in the ECM programming, but have any other changes occurred lately?
EDIT: The more I think about it, the more I'm starting to wonder if a wire could've come loose. Probably wouldn't hurt to physically check all of your ground connections & maybe even some of your connectors...
