Honda won't start if it's recently been running - any thoughts?

No. You either let the engine warm up after a cold start, buy an aftermarket modification to the injection programming, or remove the spark plugs and dry them.

Fuckers.

Wait a minute! Did you do barbitu8’s gas vs. electrical test? I have a ‘92 Honda Civic that will do exactly the same thing as your car, especially in the summer. Lots of crank, but no start if I try starting it right after turning it off. I can usually take care of the situation by opening the gas cap, which releases pressure inside the tank, then screwing it bak on right away. Got this one from Click n’ Clack. I think they called it “vapor lock”.

Please realize that it if the main relay is at fault, your fix “works” due to the opening and closing of the driver’s door and the time it takes to perform your gas cap ritual (i.e., it may be just as effective to get out of the car, walk to the rear, open the fuel door, do 25 push-ups, get back in and try starting it).
