[s-cars] Stalling 100CSQA (2.8 12V V6, 4sp auto)

Perhaps a virus going around?

A friend's 1998 (C4) Avant is doing something 
similar.  It has been dying on the road on and off 
for a month or so.  She pulls over, waits a bit, then 
drives off.  Fuel pump, right?  I'm not so sure.  The 
problem can happen twice in one day, then disappear 
for a month.  When I pulled codes, there were misfire 
codes for 3 cylinders.  POS?

I think I am going to put a fuel pump in for 
starters.  POS failure is not something you see with 
regularity on the 12v, and the car does have 198k on 
it, so a fuel pump can't hurt.

I'll post results, please do the same.

Posting for a friend's '93 100CSQA, sounds SIMILAR to 
Bob Rossato's
friend's 90Q, except I don't know if the 90 is a post 
95 (V6) or
earlier (I-5) car.

Friend started his car this morning, started rough, 
ran, tried to back
out the driveway, and only got about 10' (3 m) and 
stalled.

Tried re-starting the car several times, cranked, no 
results. 

He and his wife tried to push the car back up the 
drive (it was in the
way), tried for a short while, then, on a lark he 
tried to start the
car again. It started rough, then ran, and he was 
able to get it back
up the driveway. He didn't try to continue running 
the car because he
was already running late, so he took a different car.

I THINK it too sounds like a possible FPR issue, 
although the Fuel
Pump could be an issue as the car has 193K miles on 
it.

Any ideas?
