Sam Lambourne told me to start eating right from the start to 'keep your gut interested'. As the body tires blood is fed to those areas working hard,mie leg/ arm muscles, and away from other areas, such as the stomach. By eating little and often you keep the stomach engaged, and therefore a small blood supply at work.

Queasiness on the longer runs can come from having undigested food in the gut.
Some trial (and error) required, but it supports Dan's thesis to some extent.
