Electrical anomalies ?

[AV8R4AA]

On my 2003 4.6 sometimes I get strange (self repairing) electrical glitches.
The other night, I drove the family to dinner. All fine, no issue.
Shut off the engine and ate dinner.
Started X5 up, got a message about self leveling malfunction.
Stopped, restarted car, all fine.

I had the kids sit in the car and it was running. Cold that evening.
Came out with a trifecta glowing dash.
Drove home, restarted, all clear.

No reason for glitches, I have a 6 month old interstate battery, 2 month old alternator.

The electrical system is stronger than Jack LaLane.
Most outings, never a glitch, last one had 2.

Anything to check out?
