I have a 2007 Acura TL Type-S with nav. Upon starting the car and driving it for awhile (happens sporadically and randomly) the nav and radio will turn off, but then turn on shortly after (1min-15min) again as if nothing happened.

The radio will keep its memory on stations so its not losing complete power to it, it is more like the radio and nav are thinking that the car has turned off, not lost battery power. The heat and ac still work as well when the screens go out, but since the screen is off you cannot read the temp or radio settings displayed.

I cannot figure out what the issue is, maybe a loose wire or bad control module? Does anyone know what could be causing this and a possible fix or troubleshoot?

thank you guys.
