My first thought was to ask if you're sure it's a fuel issue and not something else temperature-related, such as a bad coil, but I guess the nose-up no-start symptom nixes that. So...
Once you get the symptoms and have stopped nose-up on a hill, do you still get good fuel delivery? If you do, it sounds more temp-related than gravity-related... maybe the fuel is bubbling in the float bowl because of the high underhood temperatures. I haven't had this happen on my 95, but have on my Sonett; had to put a phenolic insulator between the carb and manifold to cool it off a bit. You can order these insulators from Pierce Manifolds.
If fuel isn't getting pumped, then more likely it's gravity. This is going to sound wacky, but here's one possibility: Maybe your fuel pump is upside down. Some previous owner had done my 95 that way, with the supply hose going into the top and the outlet hose coming out the bottom. When the fuel level in the tank was really low and the car was going uphill, this was just enough to interfere with fuel delivery -- the pump couldn't suck hard enough to raise the fuel the extra distance. I took off the pump and put it on the other way, with the supply hose going to the bottom pipe and the outlet taken off the top, and this seemed to help quite a bit.
