TIPM is probably getting moisture or has corrosion. I know they had a problem with fuel pump so there is a add on relay to convert relay from TIPM to external. Some say dealers will fix for free but that was couple of years ago. Dealers had everything. Here's the story.
Ooooft…. Thank you for the reply and information! I will pop it open and take a look round in the unit.

I'd say MAP sensor slightly out of range since at high altitude it was fine yet sea level it acts up.
I chased a bad MAP on my Chevy 5.3 that set no codes in any of the code families, yet it killed 3 mpg and would not complete the emissions monitors.
Only way I found it was with my autoenginuity scan tool that has 2 MAP tests, and it would erratically fail one of the tests.
