Authentication lost Google app script - authorization

Question

I have created a a google app script that create a pdf from a google sheet and send it via email.
I have three script that work perfectly. But with the fourth script (identical to the other)I lost always the authorization after about one - two hours.
Has someone the same problem?
Thanks
Pasquale

Attached code. I use a trigger to lunch code every time the form is submitted.
// When Form Gets submitted
function onFormSubmit(e) {
var docTemplate = "1mI4SQQe4muuW386jgzkxBlZBWuH0OBRdbz1hItOPjK4";
var docName = "DDT";
var ss = SpreadsheetApp.openById("1HzZFDJYAU6H1pptqcA5fEAVelkZw1LP7si9bBrsF_u0")
var sheet = ss.getSheets()[0];
var lastrow = ss.getLastRow();
var d = new Date ();
var id ="0B1-7TPSHWZ1bMlNLTV9tTFJNb2c"; // cartella Raccolta DDT
var folder = DriveApp.getFolderById(id);
//Get information from form and set as variables
//var email = "pasquale.martucci#decathlon.com";
var email = e.values[1];
var mittente = e.values[2];
var destinatario = e.values[3];
var primaQnt = e.values[4];
var primaDescr = e.values[5];
var secondaQnt = e.values[6];
var secondaDescr = e.values[7];
var terzaQnt = e.values[8];
var terzaDescr = e.values[9];
var quartaQnt = e.values[10];
var quartaDescr = e.values[11];
var quintaQnt = e.values[12];
var quintaDescr = e.values[13];
var aspetto = e.values[14];
var colli = e.values[15];
var peso = e.values[16];
var vettore = e.values[17];
// Ricava indirizzi e città
var cell1 = sheet.getRange("S"+lastrow);
cell1.setFormula("=VLOOKUP(C"+lastrow+";Foglio2!A1:C35;2;FALSE)");

var citDest = cell4.getValue()
//Ricava data
var day = sheet.getRange("W"+lastrow);

var month1 = sheet.getRange("X"+lastrow).getValue();
var year1 = sheet.getRange("Y"+lastrow).getValue();
var data = day1+"/"+month1+"/"+year1;
// Get document template, copy it as a new temp doc, and save the Doc’s id

// Save and close the temporary document
copyDoc.saveAndClose();
// Convert temporary document to PDF by using the getAs blob conversion
