There's no way to tell what the problem is with an intermittent failure based on just the script. Run in debug mode and see if you can capture the exact issue.

Try to debug right hand side you can find in script editor 

And check where it is getting failed 

Or try to load with limit load to check this issue.

Or else give more details on your iusse
