Unhappy 380SL - starving for fuel

Hi all
my 84 380 SL seems to starve for fuel when driving. However when stopped it idles fine and revs fine. The funny thing is that at times it runs OK. The problem is intermittent although it seems like it is doing it more now than less. I replaced the fuel filter and heard the fuel pump making a buzzing noise. Any ideas? I'm afraid to take it to a shop--trial and error are killers. Thanks

The fuel filter was a logical first step. Are you sure it's the fuel pump making the noise? If you are that could well be going out. If not get a mechanic's stethoscope and isolate the buzzing noise. You could also check the fuel pressure as it enters the engine because there might be some sort of restiction somewhere within the fuel delivery system.
