2007 S550 command problems.

I have a 2007 S550 with roughly 85k miles. Recently the car's computer system has been resetting while I am driving on the highway. The entire command/nav system and even headlights turn off then turn back on as if I was just starting up the car. I also feel a stiffness in my steering wheel as the car is resetting itself. All the while my speedometer/tachometer light cluster and other gauges stay illuminated . On some occasions when the command shuts down my Esp/Abs lights will come on over the dash and then it will recycle itself off. No issues with the engine while driving but this is a very concerning issue. MB Dealership could not find anything.
This all happens at different times while driving. Sometimes it's about 10 or 15 minutes into driving. Mainly it doesn't appear to follow a constant pattern. Sometimes I can drive for an hour with no issues. I have seen a similar situation on YouTube with another owner of a S550. It's like my car has a ghost in it. Someone please HELP ME!
Does anyone know of any similar problems with this vehicle OR any advice?

Deja vu? Didn't we already have a thread on this? Check the battery terminals for intermittent contact. If the terminals are snug, getting it to a shop for a diagnostic would be next.
