Log it and get the specific code. One of two things happens at that speed based on what you've said:
1. Trimmed out which means open loop settings will need to be adjusted
2. Your car overheated or obscure fan issue?
I suspect the later based on the light going away after 2 min and the fan code. Also you have very high IATs from what I had seen. What transmission do you have and do you have the stock oil cooler?
