[s-cars] stalling

[stefan13 at att.net]

I just returned from a lovely trip on AAA's finest new towtruck - really shiny.  While coming to a full stop at a stop sign, the S6 stalled and died.  It would not immediately restart.  As I was waiting for the truck to arrive, it would restart but only run for about 3-5 seconds.  I checked the usual little vacuum hoses as well as the fuel pump fuse.  Fuel pump relay?, fuel pump? exorcism? (not necessarily in that order).  As always, any help is appreciated.
