Welcome to the forum. Could also be a flaky fuel pump or relay. Also check for any cracked tubes leading into the intake.

Spark plugs are at the end of their service life, pull the 3 out that don’t require removing the intake and inspect their condition.

Check air filter, who knows the last time it was changed.

Manually put the ignition in RUN without stepping on the brake, do you hear the fuel pump energize and pressurize the fuel system for 2 seconds before going silent?

If yes, put foot in brake and start it. Does it stay running or stall?

When do these stall events happen, in the mornings on first start of the day or any time regardless of previous runtime?

Its got an aftermarket cold air and yes the filter is def in need of cleaning
Rite now seems random, but previous owner said it becomes more common in cold. It will start fine and then shut off, but after few times will start and run fine, im still playin with all the diff scenarios to get more info. I will keep updating, dealer suggested it mite be the win module which apparently is expensive fix

Pressing the butt of the FOB against the start button and starting it that way bypasses the WIN module. If you get to where you can make it stall on command, try that trick. If it won’t stall then, it isn’t the WIN module.

Oh really sweet little trick. I seen a YouTube clip where buddy showed that trick to do a start with a dead fob.. Only thing is his fob and push button are totally diff then mine, that's actually another thing im trying to figure out, apparently my push button pops off and u can insert the fob like a key...

That’s odd, I thought those went away with the 2010 year models...oh well, same thing, if you can use that FOB to start the by popping off the start button, the WIN module should not be a factor. So if it stalls after doing that, the WIN shouldn’t be the culprit
