Cat Acert C-13 intake valve actuators issues

I know its a common problem on c13 and c15. I can not get it figured out though. Sometimes it won't code at all and runs great then at times it codes out really fast once it starts pulling. Some reason it will code out and then derate. Then it turns back off shortly after. But once it does it a 3rd time it stays on until I restart the truck. Sometimes it will run long time before it does it and then the next starts doing it again right after I restart it. Im starting to think its a wire or something. I have already replaced all of the intake valve actuator solenoids, along with the oil pressure sensor under valve cover. Just replaced both wiring harnesses also for the actuators. Where do I begin to look next? Some people have thought it could be the ECM messing up? When it does code out and I check the codes. It shows, 92,93,94,95. Thank You.
