PHP in IIS server stops randomly

I have a Windows 2008 VPS. I have installed IIS on it.

PHP stops working randomly on my IIS Windows 2008 server with no error.

I created a ticket with my hosting provider, they are saying -

As discussed, we could see PHP error in event-log:

You can create dump file of w3wp.exe and it will create dump file at C:\Users\Administrator\AppData\Local\Temp\2 for further analysis.

I don't see any error in my PHP log files.
