On my 2007 chevrolet Impala, with a 3.5 v6 engine the traction control service light comes on , and if I keep driving the engine will stop running
SOURCE: Service Throttle Control
It sounds like these things are all related. When the a computer sees a problem in the Electronic throttle system, it will dissable traction control, and give the reduced engine power alert because the powertrain computer does not know the value of throttle postion.
Codes will need to be scanned in the computersto begin diagnosis.

po455 is Probable Cause[s]
1. Defective, loose or missing fuel cap
2. EVAP canister broke, hose cracked or not connected
3. Purge or vent solenoid defective
4 . Vacuum leak at engine po121 code po121 means Throttle Position Sensor/Switch A Circuit Range/Performance Problem . it is usually indicative of a faulty throttle position sensor or faulty wiring harness in the engine bay.

You'll need to have the codes read from the computer. You will have a code that indicates one of the front wheel sensors is bad. This could be the case, but they are very expensive as they are built into the wheel bearing assemblies. It is more likely that the wiring harness between the frame and the part of the front spindle that holds the harness, has broken internally. It is a very common problem and can be repaired with a new wiring harness section or by tracking down the fault and repairing it.

Traction control only works when one wheel is spinning faster than the other it trys to even them out so it wont spin...sometimes if one of the wheels come off the ground in an uneven area or if you take a turn too fast and one wheel turns when the other one dont it is designed to operate.
I would remove all wheels and check the braking system...Is it 4 wheel disc or rear drum ?
If it has rear drums you could have a wheel cylinder leak that will sometimes lock the wheel because of fluid contamination....This would cause both lights to come on...If you find no problems
sometimes the abs sensor builds up fragments on the magnet and makes the light come on...
or if the abs sensor is not close enough to the exciter ring it will make the light come on because it will be out of adjustment.....all you do is press the sensor inward until it barely touches the ring and it will adjust itself....You can sometimes clean the magnet if it is contaminated and make the light go off ( only after you reach 6 to 15 mph. it will go off ).If it dont go off you have to buy a sensor.
Also make sure all tires have same amount and plenty of air to keep vehicle in balance/level.
