Welcome to our site my name is***** will need a fuel pressure tester and a good scan tool o trouble shoot this problem. The most common things that will cause this is High Pressure Fuel Pump, Timing Chain and Camshaft Phaser. Sounds like the phaser or other timing components. But it will need diagnostic testing. I can help but an advanced scan tool will be necessary. I may be able to help you to find someone in your area that won't be so expensive.
