The compressor is starting, stays running about 25-30 seconds then quits. I have replaced the battery, the oil pressure switch (with the original sullair part). Still this won't stay running. Any help?

Welcome to HEF southernohioce :cool: .

Have u unhooked the automatic throttle control to see if it’s related to the inj pump or throttle control.??
99% of the ones I’ve worked on are FULL OF WATER..(rust)
U can adjust the screw to get it to low idle.. run/adjust it to about 1000rpm and wait to see what happens
If it has a Stanadyne/RoosaMaster inj pump, try to get the # off the name plate..
