String trimmer stops during mowing job

I’m trying to mow and trim my 1 acre field. The mower works but the string trimmer turns off and doesn’t restart. I have the entire boundary and most of the no-go set for trimming. I had to power cycle the core and then the trimmer worked for a few feet and shutoff again. There aren’t any errors shown in the app.

Any ideas or suggestions?

Power down, pull battery cable for 5 mins. Disconnect the trimmer module connection cable and reattach it. Make sure it clicks and is secure. Try again.
