Saturn Kills on Freeway

Hey Everyone,
I have a Saturn L300. Often times when I'm driving down the freeway the engine will just kill for no reason. It will start back up again. But this seems very unsafe...let alone anoying. Anyone heard of such a thing or know what might be causing it??? Thanks!

what year?

2002

My wife had a 2002 L200 (before her Vue) and had to have the fuel sending unit (I think that is what it was called) replaced under warranty. Apparantly this component sends a message to the computer, and if it thinks it's out of gas, the computer cuts the fuel pump. It died on us three times before we went to the dealer. The first two times the gas was really low, and I fugured it was just a hiccup, but the third time there was a full tank of gas. This cured the problem.
