Background task cancelled (ExecutionTimeExceeded)

I got a background task that downloads a few JSON data files that works perfectly when I call it using Visual Studio. When the background task is called using the UserPresent trigger at startup it gets cancelled (ExecutionTimeExceeded.)

Is there anything I can do to run the background task without any limit?

Probably not, the time limit is dependent on trigger type, and as MSDN says it can vary from 30 seconds to 10 minutes:

CPU quotas: Background tasks are limited by the amount of wall-clock usage time they get based on trigger type. Most triggers are limited to 30 seconds of wall-clock usage, while some have the ability to run up to 10 minutes in order to complete intensive tasks. Background tasks should be lightweight to save battery life and provide a better user experience for foreground apps. See Support your app with background tasks for the resource constraints applied to background tasks.

The backgroundtask should be a lightweight code - maybe you can redirect file download procedure to background transfer service and do some of heavy job in main app. You may also try with MaintenanceTrigger, there is a chance that constraints are lower for this one, but it fires once phone is connected to AC.
