There's currently no timeout method in Netsuite for serverside scripts. What you can do is set up a variable that holds the end time and check on it from time to time like. Something like this:

var maxExecutionTime = 90; //In Seconds
var endTime = new Date();
endTime.setSeconds(endTime.getSeconds() + maxExecutionTime);

if(new Date() > endTime){
    //exit
}
