Does it happen on different designs? It may be the design is dense in that spot.
Is the bobbin low? My machine gets cranky sometimes when the bobbin starts to run low.
Is there any thread in the bobbin area? Even a small piece can cause issues.
Is the machine set to cut the jump stitches? Is the cutter working?
I would cut out all the bad orange stitches in that one spot on the back and restitch just that section. Slow the machine down so you can catch and stop the machine when needed.
Just an FYI: You may want to add a layer of WSS clear topping on dense designs. It keeps the stitches from sinking into the fabric. It is not necessary but just a tip.
