81 380sl The Car Runs Great For About 2 Miles,then Starts To Loose Power. Restart Cures It For About Another Mile And A Half.

fill up the tank and add a bottle of Techron fuel line cleaner. if that's the problem you'll see a very quick improvement

And has your fuel filter been changed recently?

Parts That Have Been Changed; Fuel Pump,filter,dist Cap, And Rotor. I Have Checked Fp Relay& Ov P Relay. SEEM TO HAVE GOTTEN WORSE WITH NEW PUMP & FILTER.

but have you tried the Techron?

If your fuel injectors are clogged a new filter won't help until the injectors are cleaned out. Try the Techron.
