BL4 736D My serger will sew for a while then slow down and stop completely.
I have the same problem with my second hand baby lock. I found this forum http://sewing.patternreview.com/SewingDiscussions/topic/34282 and the problem seems to be with the "brushes". And they are a $15 part. But you will have to pay for the labour also which someone said cost her about $100.
Your serger needs service. (clean, oil, adjust, etc.) It may be that the motor is not lubed well enough and as it is being run it heats up and expands which causes it to bog down and stop. I would take it in for service and "mention" this issue while you are there.
Babylock actually had a recall, on this issue, on the fabulous BabyLock Pro Line, but a few other models had it, too, it is the feed dog eccentric cam, and parts it move against, are different metals, and over time, they develop metal burrs, which heat up, and swell, as the machine runs, which is what slows it down. It will eventually seize, right there, if not repaired, but it is a relatively quick, simple repair.
The stitch length eccentric cam and the bushing, need removed, polished with superfine sandpaper, then greased, and reinstalled, just be sure they are smooth enough to move against each other. This should last many years.
The white plastic cap, with a red arrow, on the stitch length adjuster, needs pried off, which reveals the screw that needs removed, to pull out the eccentric cam, to polish these.
I blogged about this, on my Tumorfarmer blogspot Vintage Sewing Machines blog, with links, to a tutorial, as well as a description of how to do this repair.

Did you ever get your sewing machine to speed back up...mine does the same thing Singer Quantaum 5430, runs great for about one minute and then so slow I can't run it any longer

We had the slow issue and it was the foot pedal. But, rather than replace the pedal I disassembled it, cleaned it, then found a little adjustable pot (resistor). I used a tiny screwdriver to adjust the pot and the speed increased. I noticed that there is a slot in the bottom of the pedal housing that is for accessing the pot without disassembling the pedal. My wife sewed a dress after the repair and so far it is working as it used to.
