ECU burned up

The magic smoke came out of my 4runner's ECU today - I was in the woods, and the A/T Oil Temp, Battery, and Brake lights all came on. Battery gauge was about halfway. It died, and wouldn't crank, so I had a buddy jump it. It jumped fine, and ran for about a minute before the dash lights came back on. I tried to get it turned around and back out of the woods, but the idle started going funky (up and down up and down) and it died.

This time when it died, none of the interior lights would come on, and it wouldn't do anything when you tried to crank it. We pulled the underhood fuse panel, and noticed that the alternator fuse was blown, as was the EFI fuse. We jumped these two fuses with wire, and it would turn over, but not crank, and then the ECU let out a wonderful puff of smoke.

I'm sure I fried my ecu, so I just bought one from ebay. ANy other ideas?
