Difficulties with task initiation can be the reason for procrastination, as can being averse to whatever task you're procrastinating.

In Factorio's case, though, I'm not sure if it's necessarily either. Speaking from my own experience, a non-trivial amount of my playtime is spent not really doing anything while I think about how I want to do things, and the realization that I didn't get anything meaningful done in a given session can make it harder to find the motivation for subsequent sessions. You can help avoid that by making a definite to-do list and thinking about what needs to happen to complete each step outside of the game, then you've got specific tasks to tackle once you load it up.
