What usually causes the sudden loss of power and the stability message here can be a fault with the throttle body itself.The throttle body electronic sensors can fail like the throttle position sensor and cause this issue here and is common.In some cases you can have the throttle body cleaned to clean the carbon from the bore and bore plate to correct this here and in other cases it may need replaced as an assembly.
What needs to be done from here is to have the fault codes read out/checked with a scan tool that can plug in and communicate with all computers in your vehicle to see what codes are set.Once this has been done any codes set will need diagnosed to locate and repair this fault here.Most shops or a dealer can check the codes and do the diagnosis as well for this fault here.In some cases you can get the fault codes read out free of charge from a local parts store as well like Auto Zone to see what codes are set then diagnosed and repaired from there.
The codes do need checked to help locate the fault here for repair.
