I cammed my truck less than a year ago, but recently it has been shuting down while coasting, typically between 15-25 mph, I am running the stock converter and never had any problems until recently.
It has shutdown 3 times already while in traffic so thats not good safety wise . everything works prefectly fine in my truck other than it shuting down.
Could it be the tune?? Any suggestions??

Get some one who can read your MAF Hz

and check the fuel pump output.

My Tahoe would do this kinda thing stock and replacing the MAF and pump fixed everything, but verify before you buy parts on my account

Truck has been tuned previously but i think i found the problem, I should have cleaned the throttle body before i got it tuned. I cleaned it today and damn it was dirty but i noticed that the throttle would stop at a certain point due to all the crud and dirt, once i cleaned it, i could push the throttle all the way back but it still stayed in the same position before i had cleaned the throttle, problem is that it does not close completely it stays open which causes my truck to rev to 2k in park or neutral, hopefully a retune can fix the issue

The throttle body looks like its in decent shape, never had a problem with it so I dont think its messed up hopefully , but it was very dirty , im going to take it to my tuner’s shop, hopefully we will just need to relearn the throttle and hopefully its a quick fix, either way ill keep you guys posted to see if this fixes the problem

Luckly It was the throttle, my tuner adjusted the the throttle body a little, now it works completely normal and has not shut down thank God.
