Could be:

1) fuel pump.  I know you replaced it 3 years ago, but I've had problems with
   them right out of the box.  Take it out, inspect the points, check the
   tensioning of the diaphragm and check the diode and/or capacitor (if       
   possible.  There was a thread on this recently.

2) an obstruction in the fuel lines.  Blow out the lines with air.  Check for
   even a small dent in the metal lines.

3) a sticking needle valve or valves.  Inspect/replace if necessary.  Consider
   Grose Jets.

4) Remote possibility: an intake leak that only manifests istself when the
   engine and manifold are hot.

Good Luck.
