Years ago, I had an Isuzu Trooper that developed very similar symptoms. I replaced and serviced the same or comparable parts as you, but it didn't permanently fix the issue. Then, because every logical remedy had failed, I wiggled and then unplugged the harnesses from the main ECU, reconnected the harnesses, and the problem never reappeared. For me, the ECU was easily accessible and easy to disconnect/reconnect. Also, the technology in the car was fairly basic compared to today, but you could be dealing with something as simple as poor connectivity to the main ECU. It's worth a check, IMO.
