That could still be a bad wire/connection. It was made by man so even new can be suspect, especially with the quality of "new" that is out there these days. I cannot count how many brand new parts did not work or failed within a few moments of being installed.
It sounds like it is heat sensitive part. Normally I would suspect the crank sensor but you have changed that and it still does it. The harness is the next place to look, a wire that is hitting the exhaust or a sharp spot on the engine or is pinched between parts could act this way.
It is also possible that the ECU itself has a marginal component in it that is getting hot and failing. If your scan tool shows live data you could watch the crank signal and engine temperature along with attaching a scope to the crank sensor. Run it until it shuts down and see if the crank sensor signal goes away before that happens.
