Is there a Check Engine Light/Service Engine Soon light on? If so a scan tool will be needed to retrieve codes stored in the computer of your car. The codes stored in the computer would indicate where the problem is or at least give a basic starting point to do tests.
My guess would be a failing ignition system, failing fuel pump or pressure issue, restricted exhaust or cat converter or engine mechanical issue.
