So glad you chimed in earlier today, saw your post and planned to check on it. On the way home in rush hour traffic it happened again and wouldnt restart, got it off the road and checked that ground. It was loose..
I had installed the Optima from my XJ, and some HD terminal ends from Wal-Mart. The wire from inner fenderwell pulled right out of the terminal end... apparently i never tightened it enough.. yeah i feel stupid.
That wire is a bit short so i think i'll replace it..perhaps thats why it became loose.
Question: Both the black grounds were very warm, while the pos cable was cool?

I picked up contact cleaner and dilectric grease a few days ago, plan to do just that.
