I have seen fuel pressure issues cause this. Fuel filter, or fuel pump. However, I have also seen the catalytic converter cause this issue. The honeycomb, located inside the catalytic converter, breaks up and will block the exhaust when you accelerate. Engine power is lost, until you let off the gas and let it idle. Then, the chunk falls down from the exhaust port, and it runs fine again. Until you get on the gas and increase the velocity of the exhaust, and the chunk blocks the exhaust gasses again. Good luck

i would say that you have a bad fuel pump or if you have a carb on it the float inside the carb is stuck check these and i'm sure you will find it's one of these.

The most common source of that problem is a sticking idle control motor. As a first step, purchase a new gasket and/or O-ring for the idle control motor. Remove the motor and clean it out using aerosol carburetor cleaner. If the idle control motor was sticking, that should cure it. It the fix only lasts temporarily, you need to replace the idle control motor. This is a common problem with vehicles with over 80,000 miles on them.

SOURCE: The engine runs fine until it get to half a tank of gas.
I wonder if it could be that the tank's not getting vented properly... have you tried just taking the gas cap off and replacing it, without adding fuel? is there a suction sound when you take the cap off?
