Fuel pump going bad? Bad ground?
Check fuel pressure when you first turn the key on, and then see if it
slowly rises during those 5 seconds. After the car dies, see what the
pressure is. If it stays constant around 40 or so, then it's probably
not a fuel pump issue.

New prob on the '00 S4: engine dies randomly.
It started a couple of weeks ago; I was cruising down the highway and
suddenly the engine cut out and the tach went to zero, then just as
quickly it came back. No CEL, and no codes with my generic code reader
(yep, I've gone 123k without a VAG-COM; ordering on this morning). Ran
fine for a week or so, then did the same cut out-back in once last week.
Same thing: no CEL, no code.
Yesterday, however, on the way home from work it simply died. No
warning, just ignition dead, didn't come back. Key was still on, and
there was pwoer to the dash; fortunately I was on city streets so I
simply coasted to a stop. I was so surprised by it that I neglected to
hit the clutch and a few seconds later the low oil pressure warning came
I tried to restart it; it turned over (starter and battery are good) but
wouldn't start. Third time it "caught" then immediately died, then
wouldn't start again. Finally, for whatever reason I decided to turn the
key on and let it sit for about 5 seconds, then when I hit the start it
ran. But, as I drove away it died again and I was stuck for another 2-3
minutes trying to start it.
Then, when I tried to leave the house today, same problem: no start, but
when I let it sit with the key on for 5 seconds or so it would start
(could just be a coincidence. And it ran fine all the way to work...
As noted, I'm ordering a VAG-COM this morning. However, until I get that
I'm looking for any similar experiences that anyone's had with this?
