'91 300e 4matic

For the first time, the car started from cold rather poorly twice yesterday in the Am and the Pm, requiring a lot of extra crank but finally catching and then running normally.

This am, same thing, a long cranking session and then idling rough for a few secs, then normal. But after I drove around the corner, it died and wont restart. Plenty of crank... electrical system is seemingly fine.

My hunch is it's fuel delivery related...any thoughts?
