My car had a similar problem, started fine in the morning or while running errands, but after 8 hrs of sitting it'd start then die, as you described.
Your brake booster may have a leak. Try clamping off the big hose going to it and see if that helps. It probably won't but it's definitely worth trying.
The other thing I've found is that the instant the fuel pump kicks on a big pressure pulse shoots through the injection system. If the pulse absorber thingy (accumulator) isn't working correctly the injectors will squirt a little fuel before the starter is turning. Combine that fuel with the fuel from the cold start valve and your mixture is too rich. Pull an injector, switch the key on and see if it squirts.
