Random stalling issue
For a few months now every so often when I first crank up my car after I have drove it about an hour prior the engine cuts off once I give it gas and begin to ease off the clutch. It usually happens when I am on a slight incline. It's not a stall becuase am in not bogging the motor down. The engine simply is cutting off. I have to restart and try again about 10 times or so to finally get going down the road. Other than this only happening when the motor is heated up and on a slight incline is it never happens any other time. Once it gets moving the car is back to normal and will not do it again from any stop lights.
What would cause this odd behavior?

I clean the MAF and TB every other oil change. The car has a brand new LS6 with roughly 15k miles on it now. TPIS headers, high flow cats, ported TB, x-pipe, borla stingers, Taylor plug wires. The car has been tuned as well before it was ever turned over. But the car does idle and drive perfect. Just this wierd random issue happens every once in a while. I will check for codes tomorrow but it isn;t throwing a CEL.

Hmmmmmmmmmmmmmmmmmmmm,,,, IF, you dont see any DTCs,,,,,, the PCM is happy. It may very well be just shutting OFF. That leads me to the IGNITION SWITCH.
How many TOTAL miles are on the chassis??

108,000 miles. I do notice time to time as well that there is a hesitation in the car starting.

I took a video of it this morning while leaving. Im not sure why the security light was staying on but it shut off every time until I locked and unlocked the car.

Try cleaning you key or try the spare key---The anti theft system may be licking in--These keys have an OHM reisitor built into the key-- Also--when it dies--does it stumble /idle hunt breifly then die ? OR does it shut off quickly ??

You have a theft deterrent issue. Its doing the 2MPH fuel cut off. The security light should NOT be on and when it was on in the Vid, the car stalled when you tried to roll forward.
When the light was OFF,, the stall issue no longer was an issue.
Sounded like you locked and unlocked the car with the FOB. When you did that,, the security light went out and was NOT on as you drove away.
You have a problem with something causing the theft deterrent system to remain ON when it should be OFF.
