Matt,
My 1st guess is you may have a fuel vapor problem
unless your vent is blocked. After a good look around, I would look at
cooling the gascolator and protecting fuel lines from heat. I doubt your
wife would find vapor lock at 12,000 ft very entertaining. (If that is the
problem) Just a thought to add to the list.

I normally have had around 4-6 psi flying around my airport, however,
yesterday, I flew on my first cross country. Cruising at 220mph, I noticed my
fuel pressure slowly start to drop as I got faster and higher. It went down
to 2 psi. I climbed higher in case I needed time to find a place to land.
Luckily I didn't.
