I changed the alternator, put a new battery, change the gas filter and cleaned the throwtle.



The car dies when drinving. I have to wait about an hour then it starts up again.



I have no idea what could be causing this. My mechanic hooked up to the computer and no codes came up.



Any ideas? preferably, have you had this problem? How did it get fixed?
