I also have a similar problem my 1987 560 SEL was driving fine then on a slight hill it died. When I tried to restart I noticed the low fuel indicator on and it would not start (the fuel gauge is at half tank which I think is accurate). I tried again in 15 min. and it started I drove for 1 minute and it died again. The low fuel indicator is now off and it starts fine. I'll drive around and see if the problem still exists. Where should I start to solve this intermittent problem?
