[s-cars] '95.5 S6: No warnings, no symptoms just won't start - help

[mkaehly at comcast.net]

Late night burrito run to Chipotle. . .a non-eventful 1.5 mile trip. . .

Shut off the car for 5 minutes, get back in with burrito in hand, turn the key and she won't "catch".

I have juice, not out of fuel, no smoke, no smell, all the warning indicators (pre-ignition including CEL so I assume it see's the ECU) are correct.  The only thing I can hear different is a "whine" when I turn her over - like a belt rubbing whur.  She has never let me sit before and the spontaneity of the problem make me think it's coilpack or timing or fuel pump - but absolutely NO warning signs (at least that my amateur senses could discern).

Anybody experience this thing before?  Do you think it's one of those "I'm in Audi hell for 3 months" type of e-mail subjects or am I just being a pragmatically-pessimistic-optimist? 

I was going to have her towed to my house but thought better of it since it was not a "I know exactly what the issue is and I'll order the part myself" issue.  So I had it towed to the closest place to me that knows how she works (AutoSport Werks in Broomfield, CO).  At least I saved the extra 150.00 on another tow charge, eh?

Any help is, as always, greatly appreciated from this gruppe!
