Frigidaire freezer not working

My upright freezer works fine in every other way, but when it comes time for the compressor to kick on and start cooloing, it only does so for a few seconds. It then shuts down, blows air, and will cycle back on in a few minutes. It runs again for a few seconds and repeats the process. Does anybody know what part(s) I will need to fix this? Thanks, Brian.

Most likely the problem is a bad compressor start relay and the overload but there is a small chance for the compressor itself to be bad as well.
