well this problem is happening to me again.... first time 2 years ago alternator was bad... low voltage supplied....
this time the alternator was bad again and the voltage kept spiking between 11 to 17 volts... but the problem is still occurring... after reading a few articles about this issue, i read that the throttle body valve sticking/seizing might be cause of it and also the TB is tied into the abs and dsc systems... i did notice that my idle is lower than normal.. i'm hoping cleaning the TB or maybe replacing it will fix this issue... also will be checking for a ripped boot...
