Hi there! I understand your onX Offroad app stops working after you've been moving a few miles, especially if you take a break for 5 to 20 minutes. Let's dig into that and get it sorted out together.

First, could you clarify a couple of things for me? When you say "stops working," do you mean the app closes/crashes, freezes, or loses your location/tracking? Also, are you using any specific device like a tablet or phone, and have you noticed if this happens more often in areas with poor cell service?

Meanwhile, here are some initial steps you can try to troubleshoot the issue:

1. Ensure Your App and OS are Up to Date
Sometimes outdated versions can cause glitches. Since you're on Windows with a WebKit browser, make sure both your browser and Windows 10 are fully updated.

2. Check Location Services Permissions
The app needs location access to track properly. Verify that your device’s location services are enabled and that onX Offroad has permission to access your location.

3. Simplify Map Layers and Features
The app might be struggling with memory if too many map layers or features are active. Try turning off any unneeded layers or overlays in the app to reduce resource use.

4. Keep the App Active in the Background
Some apps pause tracking when they’re inactive. When you stop moving for a while, the app might be going into a paused state or disconnecting. Check Windows’ background app settings to make sure onX Offroad is allowed to run and access location data even when not on the screen.

5. Restart and Reinstall if Needed
After trying the above, restart your device. If the problem continues, reinstall the app as this can clear corrupted data.

If the problem persists, especially tied to breaks and inactivity, it could be related to the app’s handling of background location or the device’s power-saving settings. We can then look deeper into adjusting power management options to keep the app awake.

Does any of this align with what you’re experiencing? And have you tried any of these steps so far? That’ll help me guide you further!
