There could be a variety of problems, but it sounds like your in tank 
fuel pump is dying or dead. When the fuel level drops too far at the fuel 
pickup point and the prepump is not working the car will starve for fuel 
becuase the main high pressure fuel pump has little in the way of suction 
power.

Look in the trunk under the carpet. You will see a little round access 
panel. Open. You will see the in tank pump and fuel sender. You can 
usually see if it works at all by running car and listening, comparing 
with power connecter removed, installed etc. They don't last forever and 
will drive you crazy with less than 1/4 and accelerating hard.
