My s550 shuts off for no reason

[Gray5.0]

Hey guys..

so I have a manual 2015 premium GT, a while back when the RPM is higher than 4500 and I press down the clutch and come to complete stop or I want to make a U-turn the car shut off and dies!!This issue often happens and I can’t figure out why,
Other than that the car runs perfectly.

I changed the throttle body and checked for vacum leaks and everything is perfect
The car is FBO beast

Vehicle speed sensor, vacuum leaks, or tune.

I’ve had bad luck with Allen style bolts that loosen up, or even an intake manifold gasket that leaked.

There is no leak in the intake manifold but I’ll check the speed sensor
