200q20v stumbled 'til it died

I had a similar experience, except the car didn't die totally, after
apparently getting a bad load of gas while on a trip to PA from MI.
Several doses of  fuel system antifreeze and some Stabil got it running
properly again, thanks to Steve Bednarski, who provided the treatments.  If
you were running low, you might have sucked in some contaminants.  My fuel
pump was new from six months before the trip, and had made a lot of noise
intermittently, so at first I suspected I'd have to replace the pump.  I
had a spare pump and tools in the trunk for the trip, and I've still got
them in the trunk two years later.  The pump continues to whine quite
loudly at times.
