My new-to-me W210 decided to stall earlier today in the middle of rush-hour traffic, and refused to fire (but did crank).

I had to push it out of the main road and onto a side-street where (naturally) it started right up first time I turned the key, and the rest of the journey was uneventful, except for the CEL that's now lit up on my dash.

Is this a typical symptom of an impending CPS failure?
