I hope Marc fixes his problem.  I wanted to chime in that I had the
same problem as Chris with a leaking fuel line that went into a fuel
rail.  This did cause intermittent power loss is odd places, like
going up a hill, but only occassionally.  I was also getting bad fuel
mileage.  However, there was a whiff of gasoline.  So, if there is no
whiff of gas, then Marc should be able to quickly rule out the leaking
fuel line.  Of course the pressure regulator could be faulty or the
fuel filter could be jammed.

However, I think one of the symptoms was the smell of rich exhaust, so
I'd still bet my 25 cents on the AFM spring.
