MAKE SURE YOU HAVE THE RIGHT NEEDLE FOR THE THREAD YOU ARE USING, AND THAT THE SAME THREAD IS ALSO IN THE BOBBIN. CHECK UPPER TENSION, BY PULLING SLIGHTLY, IF IT'S TIGHT, LOOSEN THE UPPER TENSION.YOUR THREAD MAY BE THE WRONG SIZE OR TYPE FOR THE SPEED YOUR SEWING., and the needle your are using( sorry about the caps lock)

Sounds like as the machine builds up friction from extended use, some vital part is lacking lubrication and is seizing up. A good service person will remove ALL of the covers and thoroughly air clean and oil every moving part. Sometimes these dry points are hard to find and patience is required.
You can get a sewing machine oiler with a long applicator and put a drop of oil on anything that moves, but over oiling can be messy.
