My best guess:

It sounds like the disabler security system is activating at random times.

The security module needs to be replaced.

99 E240 & 96 E230 & 78 280se
not starting red and green lights flashing

I had the same problem with my 96 E230

Had success by replacing the electrical box (it has a bunch of mechanical relays inside it) with second hand one that I purchased from a wrecking yard,
Mine had a K3 sticker on it ( I have seen it called the K40 box) the part no to mine was A 210 540 04 72

I cleaned all the relay contacts first,

It is found inside an electrical box under the bonnet towards the fire wall, unscrew/remove top, locate relay box, then unplug the main power plug first (thicker red wires) there are several plugs , I immediately plugged in the cleaned s/hand relay box.

had no more staring problems ( so far) that job was done on the 8/2/2011

I found this on another web site (a new box was recommended) when I was having this problem, but a second hand one worked for me OK, I think it was dirty relay contacts that I cleaned before install did the trick.
