125 psi air compressor stops building presser @ 60 psi but keeps running?

Jeff, could be a number of things causing your compressor to run and not build pressure.
If it happens at the same pressure level in the tank each time you drain the tank and try again, that suggests a valve or gasket reacting to back pressure in the compressor tank.
Why not visit TROUBLESHOOTING, and click the link to "will not build pressure" for more details.
