Along with many others on the forum we all can toss out ideas of what we think the cause of your intermittant issue= this failed component. However as posted, the only way to see what is going on at this point requires you to tap into to the data stream to read "live"/captured activity as the on-board systems try to compensate for the problem. You can see injectors pulse increase/decrease, secondary ignition activity by cyl, etc, ect. All of this will help you and the collective knowledge of our community provide insight on the point of the issue.
Example: it maybe poor fuel causing an issue with a clean burn in the cylinders, or a bad injector/connection turning off fuel flow to a particular cyl, or even a bad coil/wiring pinched that fails. Who knows...
Everything at this stage with out real info is just a SWAG (Scientific Wild Ass Guess) So, based on that thought, my SWAG guess is TPS/Intake Cam Sensor related.

Help us help you.
