When I read this and think for a few seconds, it brings to mind something for you to consider. It is sounding like the ECU was "off in lalaland". What I mean by that, is like when your computer or phone "locks up" and displays a solid blue screen or simply wont respond to commands and a restart fixes it.

Now, given the history of our cars and how electrical disturbances can cause real trouble (like when I was putting my top up without the engine running and the system 'spiked', taking out my seatbelt module). With this in mind, you might consider the condition of the battery, battery cables, ground strap from block to chassis, etc. That is, look for a cause for system voltage variations.

Something that Iv'e done to my last two Crossfires is to try to secure better battery/block/chassis continuity. James1549 apparently was thinking the same thing as me and invented a mod I liked so much, I did my own version. You might consider doing his trick or my trick.
