Car just died waiting for a light

I had the exact same thing happen to me and I drive the same make and model. I am still having the same issue after replacing the alternator which later found out it the ground was off it. I found a short leading from the battery. I've replaced three batteries and still it occurs. I've stopped taking it to shops I would be bankrupt by now if I continued to allow them to list what they wanted me to do. I went out an purchase a charger that you can get a boost off of right on the spot that way I would never be left in the middle of the road at a light and being the first car didn't help. Codes I was getting was Po135 and P1131 which is an o2 sensor heater circuit. I hope this helps.
