1992 300E (193,000 mi.) sat on a train for 1 month in transit. Upon receiving the car, it ran rough and stalled with difficult restart about 2 miles from the receiving point. Car restarts rough and runs a few hundred feet, then stalls. Similar symptoms as having wet wires after washing an engine, but the engine compartment is dry. Had to tow the car home. Car ran fine as daily driver 1month ago.

Fuel filter replaced 34,000 mi ago
Distributor cap & rotor plus ignition wires replaced 28,000 mi ago
Spark plugs replaced 6,000 mi ago

I don't know where to start whether this is an ignition problem (cap & rotor) or a fuel supply (fuel pump?) problem. Thanks in advance for your advice.
