This is when you are actually doing the quilting part (as opposed to the piecing part)?
It sounds like you are learning
A walking or quilting foot might help. A larger needle might help. Even after years of machine quilting I often have issues with loops going up and away from me but I can handle loops coming down towards me just fine.
Probably the biggest help is keeping the weight of the project off the needle/machine, you have to bunch it up on your lap, over your shoulder, and set up your sewing surface so that you can support the most of the top as you can while working with what is immediately in front of you.
