Vapor Lock, Your thoughts? Options

[dcheek]

I took my 914 out for a ride on a very hot and humid day last week. I came back and parked in my driveway which has a slight incline. A few minutes later I had trouble restarting to move the car into the garage. I noticed a girgling sound coming from the tank on the initial spool up of the fuel pump before engaging the starter. The engine would fire but would not continue to run. It sounded like it was not getting fuel. I finally got it to run, and promptly pulled into the garage. The next day I started the car with no problems. My only conclusion was some type of vapor lock situation or a clogged charcoal canister?? Or, maybe the oxygenated fuel?? I've never experienced this problem before. The fuel is fresh. The fuel pump has been replaced, along with the fuel filter. And, my car has the updated (at the factory) fuel pump location up front.

Any thoughts as to why this would happen?
