Husqvarna Viking Needs a Doctor

My older "baby" is 25 years old and has been well used! It sews three stitches perfectly, then makes a little snap sound, and pauses.  I don't do pause!!!!!!  Ever!!!!!!  The stitch definition is still gorgeous and I'm hoping the repairman can give me a few more years of use.  Otherwise, this is the second machine that I've worn out!!  I always thought I was the only one ever to wear out a machine (Bernina no less!) until I met a lovely seamstress/quilter/designer at Rocky Mountain Sewing.  Nope! I'm not alone!!
