Check the vacuum line on the fuel pressure regulator for any sign of gas being sucked into the line. A failed regulator will let extra gas get into the engine. If it's okay, have the fuel pressure checked. That's sure a lot of gas, way too much for the engine. Good luck.

Sounds like you are running out of gas. When was the last time you changed the fuel filter? PO 300 means there is a miss fire which can harm the catalytic converter. It could also be a ignition problem. Coil pickup. Without hands on diagnosis it is hard to exactly pin point the problem.
