Default ECM Burn Spot

My truck died at highway speed without any warning. I found one 25a fuse under the hood blown that is for the ECM. I disconnected the ECM and heard something rattling around in it. I took the cover off the ECM and found a burnt location on the circuit board. I cant seem to save the picture here so let me know how to send it to you. The picture size is too big.

I want to find the root of the cause before I throw another ECM into the truck.
