I lifted the hood, it is my wife's car, and noticed the battery cables were corroded? The battery was old so I replaced it and cleaned everything up really good. About a month goes by and now it just died for no reason, loss of all mechanical and electrical full stop. It will start right back up no problem. NO ENGINE codes or lights this whole time BTW? There is no low fuel symptoms like chugging prior to or dimming of lights. I take it in and they say it has a low voltage meter in the alternator so I replace it. I think I am out of the woods but no dice! I drive about 2 miles and right before I get home it dies again yet starts right up? I finally get it into Toyota after a 2.5 week wait. It of course it is not symptomatic with them. They clean the throttle body and off we go and they are stumped as well. I go to the lake on the weekend. I drive about 12 miles and the BOOM it dies 4 times and each time it starts up again ON IT'S OWN! I did not even have time to turn the key off before it starts again? At least this time I do get engine light and I am stoked. Call Toyota, get it back to them with the engine light still on, turn the car off and go in.When they turn it back on there is no engine light : {. They have 2 master technicians working on it nd have called their local Toyota engineer in Portland? I am so sad and frustrated? Any ideas? If you know you can consider yourself to only a master technician but also an engineer for Toyota : }

Did you clean the battery to body ground connection/check it for being loose, if there a little bit of rust or a tiny bit loose where the ground wire connects to the body it could cause your issue.
That being said, you said the CEL came so the techs/mechanics should be able to see what caused the CEL to come on, whenever the CEL light as well as other lights comes on it stores the trouble code/s in the ECM so they should be able to pull the code/s with their Toyota Tech Stream diagnostic scanner that triggered the CEL to come on!!
Knowing what code/s triggered the CEL to come on goes a long way and sometime the only way in figuring out what the issue is without starting to throw a lot of parts at the problem until and if you get lucky and replace the correct part after spending loads of money on replacing perfectly good parts!!
