A few suggestions, first I would not drive this car until I have had it checked out.
losing power can cause hard steering and braking loss.
Some of the causes could be a dirty fuel filter and or fuel injectors, some other intermittent causes could be a loose connection on the battery or elsewhere.
If a car engine stalls when turning, there could be a problem with the power steering pump. There could also be an issue with an emissions control device.
The light comes on when the car stalls because the engine is not running and the pump therefore is not pumping. The pressure will always be 0 when the engine stalls and the light is directly related to pressure. This is normal, you have no problem, other than the engine stalling.
vacuum leak?
One reason that a 2000 GMC Jimmy engine stalls while driving could be your filter needing to be changed. The problem could also be a bad sensor.
it might be your throttle
i had that problem with mine. the problem was an intake vaccuum leak. the engine wasnt getting enough air sucked in at idle and stalling out.
Probably a clutch, but might be a problem in the trany.
It would help to know when it stalls? leaking air hoses in the engine compartment can be a problem. There are a number of them about the engine and it is about time you just replace all of them.
You are flooding the engine with fuel when you step down the pedal, and that stalls the engine. This is probably because your car timing is behind. A good tune-up and adjusting your ignition timing will solve this problem.
If the engine stalls and won't restart for several hours on a 2003 Santa Fe, there is a problem with the computer in the vehicle. Check to make sure all computer fuses are working properly.
Why engine stalls on 1993 Chrysler Intrepid while driving and sometimes at stops?
if changing the fuel filter, and it still stalls out. you have a problem with the fuel not getting to engine.
