Hello I have a sullair 375 portable air compressor. I can't get the thing to stay running. Initial start will run for a out 5 minutes then it dies then you have to wait for it sit for a few minutes it will start again and then die again . I'm a pretty mechanical guy but this thing has me baffled. Any input would be greatly appreciated
