Does seem to either be a bad pressure safety valve or you have the compressor set to kick off above it's rated pressure. If the rest of the compressor is OK for the higher pressure then just replace the valve with a higher rated one.

I have an old one lunger from the 50s that kicks off at 150psi and on at 125 psi. I have never done anything but change the oil and bearings in the electric motor once. That thing sees very heavy use for many years. It was in a junkyard I worked at and have been friends with the owners since I was about 14. When the bearins started making noise they sold it to me for $100 and the electric motor shop went through the motor for another $100 and fixed the bearings. Only other work it needed was a good cleaning. been using it myself now for about 12 years. I have another one just like it except gas powered also in perfect working order. It will probably out last me.
