Unhappy Random hard starts

On my 91' 300e i am having weird starting problems. sometimes the car will start up and run fine. most of the time it will start, stall, and then instantly restart. and once i had to hold the key for 8 seconds to get it to start. then today i figured it might be the fuel pump. i turned the key to the point before the start possition (accessory possition) and it started up, stalled and then instantly restarted. once started the car runs like it is brand new although it has staled on me twice but instantly restarted. what could be the problem? fuel pump, filter, distributer, acumulater or bad gas? what could be the problem?
Thanks in advance.

I had similar problems when I first bought my 76 450sl.
My fuel system was gunked up - a bottle of techron fuel cleaner
helped a lot. But you could have a vacuum leak, too.

If you try the Techron ($6) and it doesn't help at all, then you
can start zeroing in on other issues.

yes it will "hunt" as you described, click on the "search this forum" link and type in eha......just read what everyone else posted and you will see others symptoms as well.
