Stalling sputtering while driving with wipers and ac on

My truck came up with code p0340

Wow, I just this on my 2016 (as in today). ODBC showed 4 of that same code. I cleared the codes, and the check engine light cleared, but one code is still showing.

I had some issues starting over the past few months. Just a time or three, but it was almost as if it wasn't catching to turn the engine over. 2 weeks ago, it sputtered and nearly died when taking off from a red light. I thought it might have be the trans fluid, so took care of that. Then today, it would not start and keep running, acting like it wasn't getting gas. I finally got it to keep running and got home. It has since started and ran fine two different times.

I haven't started to try anything on mine yet, since I just diagnosed it about 2 hours ago. Still trying to decide if I can even get to those sensors myself. The wife just wants me to take it to a mechanic, so I can focus on other things. (And I am tempted. I really don't like working on any vehicle, did way too much of that when I was kid.) Check for good connections/no shorts in the wiring harnesses.

(As Grampy Matt hinted, P0340 is an error with the Camshaft Position Sensors (CPS). From what I have looked at, it could be one or both sensors bad, or a short in the wiring harnesses attached to/at the sensors.)
