Is there something specific you are trying to debug?

Short Term Fuel trims are the only thing standing out to me. Are they really going from negative 6 to positive 10 when holding 1500?

Long Term Fuel Trim going negative 0.7 to negative 3.9 is reasonable.

Yeah my truck will randomly kill off whenever it feels like it.

Can't really see anything about that when you look at a freeze frame. You really need a logging system that will record right up until it dies, then quickly troubleshoot why it died via logic.

I replaced my crankshaft position sensor and my throttle position sensor and it starts and runs fine now (still a little rough tho) so I think next I'm gonna replace the o2s and check out my MAP sensor.
