What Steve said. However, the out-of-fuel messages will continue to be generated which disrupt auto-turns, so when this happens to me I usually manual click through 1 or 5 day increments until the tankers arrive.
Sadly, you cannot stop events from disrupting auto-turns. The closest work around is to set the min-incriment counter under the auto-turn check box to some number greater than zero, forcing the game to run at least that many increments regardless of message events. However, this risks running through an event you would have preferred stopping for and also has a minor bug where any task force completing orders spams dozens of identical notices in the event log (I don't know if this was fixed in 6.4).
