W116 Cutting off

Hello All

I am new here and very technically challenged. My 1977 280se starts and runs for about 2 to 3 minutes and then cuts off. And it will not start again until after about 30 to 45 minutes. I changed the fuel pump relay to no avail. It has an M110983 engine. Can someone please help.

Sounds like a blocked fuel filter..............

110983 is a D-jet engine, so it can't be a 1977.  It must be 1976 at the newest. 

Also could be lack of fuel tank ventilation.  Try removing the fuel filler cap as an experiment. 

Otherwise, need to check fuel rail pressure, and go through the d-jet sensors and verify that they are working and in spec.
