Well it happened again this morning. This is AFTER a new fuel filter and complete inspection of my fuel delivery system by an authorized MB dealer. I'm beginning to wonder, could it be just as simple as BAD FUEL? I've been buying my fuel at the same place since buying the car in Dec/03, but all of a sudden, at the 3/4 mark with this latest tank - three roadside breakdowns. I did manage to get her started this morning after about 15 minutes of wait... crank... wait... crank. I'm at a 1/2 tank now, what can I try next? Should I refill now, with fuel from a different supplier? I use RedLine diesel additive, that should only help my fuel situation, shouldn't it?
