I finally got out today to mess with it. It seems to be the positive cable. The little fuse box right there on the positive cable. It has a 100amp which is blue. The other two were maybe 50 and 60 but I think the 100 is the problem but I know its got to be close by. I pulled all th.e plastic beneath it down and wiggled on the wires when the car died. Everything came back on and the car started. I went through that process a few times so I guess I either have a break in the wires somewhere or maybe corrosion is down in the wires but they are like heat wrapped or something, extremely tight so there is no way I can get down there to clean them or look at them. I did get the box open from the bottom and where the wires are screwed in didn't look bad at all. I never did see a drop in voltage when the car would try and start and everything died. What else can i do?
