88 300sel fuel pump realy?...

[brianandcorinna]

driving an 88 300sel, randomly will die. dosent seem to matter the temp, conditions, anything. sometimes will start in about 5-6 secs, sometimes seem to take 1 min or so. can be idling or freeway driving. left it in gear/on coming down Mt. Hood, draging the engine at about 2k rpm, and after about 6 secs it caught and kept going. Am thinking it is the fuel pump relay, but am having hard time finding it. Any ideas if it might be something else? Any help on exactly where the relay is located?
