Hello and thank you for choosing Just Answer.

 

It is likely that it's either an injector problem or fuel delivery problem. I would suggest that you start by running some seafoam through the system. Then replace the fuel filter. You can check if the injectors are working by doing a noid test. This will check if the injectors are working.

If that checks out fine you may need to have them removed and tested.
