I would run a fuel pressure and flow test, replace the pump if low, if the pump passes the test then you may have a TPS in early failure, the only way to find this is getting a live data test performed, you can see the readings the sensors are sending to the ECM and replace those out of specs.

could have a burnt valve, need to do a compression test.
