91 octane vs e85 in flex fuel Tahoe/suburban?

So, when it's cold out, in the 50s or lower, the truck stalls on the first remote start in the morning.
I take it that the E85 in the lines is really cold and doesn't want to fire. She always fires right up on the second press of the button.

I've pumped about 1,800 gallons or more of ethanol in my truck over the years. Many times the fuel sat for a month in the tank before the truck was refueled, often with another tank of ethanol. We've experienced no fuel system problems. Truck is at about 207K miles on her original injectors/fuel pump. We don't really have any metal in our fuel systems anymore. Do we?

Here in Florida, our E85 is about the same alcohol content year round. Or rather, my car calculates it to between 72 and 80 percent.

Looking forward to running it again but want to make the first 1/4 mile passes on gasoline as that's what my last passes were on. Soon.
