2008 e350 loss of electrical power
It could simply be that somehow the battery connection is not good.
I faced something a few weeks ago:
I was having some fun with my SDS and suddenly the car went black, initial instant fear factor was SDS has somehow roasted 'my entire car' how???? I used a jumper power pack and it started right up, I felt my battery suddenly packed up since it's nothing near an original battery.
Drove out that night, any stop, car would go totally black, jump, go, headlights would flicker all the way. My mind went to the battery connection which was some embarrassingly modified connection i made after some thief cut the heads off. Long story.
Short story, next morning, I just made a better connection on both terminals and that was the end of that. So depending on your charging setup maybe over time there's some slow wiggle and the connection is not good. That should be your first step, clean and tighten the clamps.
