You don't say how long this problem takes to go away. Does it?

Is there any chance that your Facet pump is located near the engine 
where it can get warm and boil off the gas and get vapor lock? It 
really "belongs" in front under the gas tank. AND I hope you have 
some kind of safety interlock on it.

Vapor lock can be made worse if the gas tank has lost it's vent, or 
if the filter screen in the bottom of the tank is clogged.
