I have received a few responses that point to heat as a potential culprit.  T=
o date I have been reluctant to believe this is the cause as my airframe/eng=
ine/fuel systems have over 1000 hours of flight time with zero previous symp=
toms such as fuel pressure, fuel flow and engine surging.  Since I have come=
 up with any other cause. I am going to look at this as a potential cause.

I will continue to update the list as I pursue a remedy.  In the meantime I w=
elcome any and all suggestions.
