[s-cars] Ideas?

[Robert Myers]

Hi Y'all,

This is a resend.  I tried to post several hours ago but haven't seen 
it so I assume something happened to kill it.  I hope you don't get 
buried in them.

Yesterday the better half and I went into our heated garage and I 
started the urS6 (RS2ed).  It fired right up and then faltered 
badly.  Pumping the pedal would get the engine revving fairly well 
but it would not idle.  Rather than take the time then (we had 
someplace to be and didn't have time to spare) we drove the peecup.

It feels and acts like a fuel starvation problem (as if the MAF hose 
had been left disconnected - it isn't).  The car was running 
perfectly when I parked it the evening before.

I plan on doing some diagnostic and, I hope, repair work this morning.

Hypotheses:
1.      Induction system hose (Samcos) leaking.  (I don't think 
so.  It ran perfectly when I parked it.)
2.      FPR acting up.  (Possibly - would the symptoms match 
that?  Where is that sucka, rear end of the fuel rail?)
3.      Out of fuel.  (Gauge reads over half tank and I believe it 
from the distance traveled since last fill-up.)
4.      Plugged fuel filter?  (Why so sudden?)
5.      Fuel leak?  (No fuel smells so no major leaks.)
6.      Failed MAF?  Is this a failure mode for the MAF?

Other suggestions?
