[QUOTE="daboyfrumdabx, post: 7151424, member: 617760"] Sounds like a bad ground or switched power source. Pull the deck and inspect the black wire and the red wire coming from the back of your HU. Make sure the wires look to be in good shape and that all their connections are secure. I don't think you'd get two units in a row with faceplates that power off. The fact that it retains memory is telling me that the constant power wire is fine(this is the yellow wire behind the deck), as that is what keep memory. A bad switched power wire or ground can both make a unit turn on/off intermittently. Not to mention that since they swapped to the same deck, they likely reused the harness that was there so any issue with wiring would have remained untouched. [/QUOTE]
