Guys, I have a strange problem and hoping some resolution. I have had alienator checked and battery replaced.

here is whats happening , while driving

1) Ist electrics all go dark
2) Orange lights then light up on dashboard
3) Nav screen resets
4) Back to normal but difficult to start.

I will run OBD when I get it back from daughter but in meantime hoping for some help

OK Update to this. This hasn't re-occurred but I'm now getting very intermittent charging light coming on. I put a battery monitor on and while driving to work the light came on. A review of the graph at the same time shows a slight dip in charging. All other tests seem normal. I would think it is a loose connection but then it should occur when going over bumps etc. but its really just random (on highway, driving 70 mph, very smooth or pulling up at stop light). Any thought appreciated

I just noticed that there is also a slight downward trend. I'm driving a lot farther tonight and I will repost that graph

I think the downward trend is normal as the battery charges. Did you check your fan belt for slippage?
