You're missing a few important pieces of information. How long is the compressor on when it's building pressure in your high pressure tanks? What gets to 65PSI, low pressure gauge or high pressure gauge? How much air storage do you have on the high pressure side?

I suspect you've mis-plumbed something or have a leak somewhere, causing the compressor to be on much longer then expected.
