Wow, that is an interesting one. I have to ask a question. You indicated the alternator was replaced. Was the alternator an OEM Denso alternator used? I remember a few years back that the alternator itself (2 new aftermarkets did the same thing). Once an OEM alternator was installed, everything went back to normal.
Do me a favor. When this is happening, I need you to check the alternator output at the battery. All you need is a basic multimeter or voltmeter.
Follow the directions in this link and let me know what you find.
These vehicles are very sensitive to voltage issues. Let me know what the voltage is with the engine running and with it off.
