Hello and welcome to JustAnswer!
The first thing you'll want to do is check for fault codes if you haven't already. You may ave an ignition system or injector circuit issue, a cam timing problem or internal engine/valvetrain issue, any of these things should set a fault code. You may have a misfire code set that will identify which cylinder you need to concentrate on, an injector or coil circuit code, etc.
If there are no codes set then I would first suspect fuel pressure or quality and the catalytic converter. It would be a good idea to test fuel pressure and take a sample to make sure it isn't contaminated.
A backpressure test can be done to check the converter for a restriction. If the material breaks up or melts then it will restrict exhaust flow out of the engine and cause a loss of power.
