Sears 10" Radial Saw Parts Answered

I have a Sears 10" Radial saw that I purchased in the late 60s. Serviced me well for many years as a cutoff saw. It now does not want to run. It starts, comes up to speed and runs for about 30 sec. with no load and then shuts down. I wait a couple of minutes and reset the protector, repeat, same results. I would love to continue to use this saw. Do you have any idea where I can get replacement parts or equivalent parts?
