A partially clogged catalytic converter can rob you of power and act like a fuel problem. A totally stopped up one will kill the engine after starting in less than a minute.

... I saw a demonstration where a mechanics only way the prove a clogged up converter was to cut a one inch hole in the header pipe just in front of the converter. When he started the engine and ‘goosed it’ chucks of pinkish gray stuff spewed out of the hole. Well the engine ran a lot better and he welded up the hole.

...  It could also be something like a Mass Air Flow Sensor problem.
