Default Check Engine Light With E85

I had read from the Chevrolet website about the horsepower gains by using E85.
So I started filling up with E85 a few times. Check engine light turned on
last time I filled up. Took it to get checked out and it gave me the code
PO50D, cold start rough idle, .. ran the tank down to empty and filled up with
Regular 87 unleaded.. after a quarter tank the check engine light turned off..
my vehicle is flex fuel, I don’t understand why it does this. 2014 Chevrolet
Silverado 5.3 4x4 LT
