Here you go on the schematic: http://www.w124-zone.com/downloads/M...am/ETM/ETM.pdf

I think the mostly likely source of your problem is your ignition switch because the W124 does not have a "start only" power feed. What works in Start will also work in Run unless the ignition switch is bad. See section 104/105.

It is also possible that is is your fuel pump relay. This relay reads the tach signal to determine when to run the pumps. It could be malfunctioning and not keeping the pumps running once the engine speed climbs, but it's not super likely.
