Puppy unexplained seizures -- death

I had a 10 week old Golden Retriever puppy that suddenly developed seizures that wouldn't stop. He was perfectly fine...no symptoms at all one minute, then started having seizures the next. I immediately drove him to the emergency vet (it was 1:30 am) who ran blood tests. The initial blood test showed a high white cell count along with a 106 fever. He had to put him under general anesthesia to stop the seizures. When I picked Bailey up at 7:30 am the next morning to take him to my regular vet, the emergency vet re-ran the blood tests--which came up normal. My regular vet also had to put him under gen. anesthesia in order to stop the seizures. I had to make the painful decision to put the poor baby to sleep that night as my vet said there really wasn't any prognosis. The unofficial diagnosis is distemper from my regular vet. The emergency vet tends to think it was a liver shunt issue. Have you ever heard of anything like this? He didn't have any distemper signs at all -- runny nose, diarehhea, eye issues? He actually went on a mile walk/run with me at 7 pm that night! Everything seemed completely normal. I am at a total loss as to what happened?
