2015 GMC Sierra 1500 Stalls No codes

[Eric Gardner]

I am having a odd issue with my 2015 GMC Sierra 1500 86,000 miles, it will stall about 20 seconds after starting, I can keep it running if i push the RPMs to 3k, even then with the foot on the petal the RPMs will dip. The truck will start right back up and do the same thing. The odd thing is the truck is not throwing any codes and the engine just stalls like its running out of gas. Oil is right at 8 quarts not over filled, nothing blinks on and off like in the videos of the GM trucks that have grounding issues. I am at a loss on this one, I have hooked up a blue driver and it reads a constant fuel pressure of 50-60 PSI. Any ideas?

Replaced the K&N air filter with a regular fram one and cleaned the MAF sensor with MAF cleaner, truck runs normal again. I will replace the MAF since its 50$ on amazon for good measure in case it was going out.

I’m having a similar problem. Did you ever figure it out? 
 

my first thought process is the lift pump in the gas tank but then I also go to my camshaft position sensor or the crankshaft position sensor but I’m not throwing any codes so I’m not quite sure what my problem is.
