Problem with estimation

I have the following problem. I am trying to estimate my model, but every time I run the .mod file the results from the posterior maximization are different. In particular the number of iterations are different (this should not be a problem) and it gives different values of the objective function at mode. Should you help me?

I am attaching my .mod file and the datafile.
