>>Been there, done that. I would second on Sergey's advice. Do not try to run a VFP service with a timer continuously. It stops working with no reason. We ended up with using windows scheduler itself (also much more flexible).

I have found the same - write a regular exe and run it in windows task scheduler works great, and a VFP program with a timer is problematic.

Just write your program as a batch - do your task and exit, no READ EVENTS.

I found writing out progress to the console and a log file to be useful.
Rick Strahl has some code on West-Wind.com how to make a console window

And be sure to use Sys(2335) to prevent dialog boxes or other UI that hangs your application. https://www.tedroche.com/hackfox7/s4g808.html

And the last catch is to use a TRY CATCH so you can trap any errors and log them and maybe attempt to email the error details to yourself.

Good Luck!
