First thing you should do is check for engine codes which can be done by yourself for free. Here is how: http://www.freeautomechanic.com/diagnostictroblecodes5.html
If there are no codes present, then you have a fuel pump going out or a clogged catalytic converter. To test the fuel pump, you will need a fuel pressure gauge or have your local shop do it for you.
To test for a clogged converter, you will need a back pressure gauge or have your local shop do it for you.
