2007 Suburban shutting down
I have a 2007 Chevrolet Suburban LT, I love the vehicle but I’m running into a problem. I will be driving down the road and all of a sudden the Service Traction Control and the Service Stabilitrac will come on the dash and it will reduce the power of the engine or completely cut out. I replaced the Battery, Alternator, and the Crankshaft Positioning sensor but still having the issue. Anybody else run into this problem? If so what was the issue or can someone point me in another direction

Wheel speed sensors at the front wheels have been known to cause this problem. You may need to replace the front wheel hubs/sensors assemblies and make sure the wiring is all intact. The wiring that plugs in to the sensors sometimes gets mangled for some reason or another.

Full spectrum code scan of all 4 code families is step one. Without that as a starting point it's just wasting money on parts and guess's.
Codes in the system will help point the way.
Just as a example the accelerator pedal position sensor will do that, common wear item, and can be erratic. It will go into reduced power mode when it acts up.
