So you are saying that it starts and builds pressure and then shuts off, then when it comes back on again, there is no pressure? Sounds like the unloader valve is sticking open.

Could be a lot of things. What is the exact model number?

it could be your compressor might be laxing slow to engage!!sometimes they need a boost! check w your local ac service provider!best of luck!!!

Might be the valve plate is worn or has a broken reed.

Could be a seized compressor, a bad start relay, or a problem with the pressure switch or a bad motor.

mostly all craftsman compressors are junk starting with the oil free ones these units are not built for heavy or continuous use good for making lots of noise collecting water and providing some heat for those cold winter days

My first question is what is the output setting at the hose end, your tank pressure would probably be around 120 but what is the regulator set at? If your tank pressure is not around 120 then yes you would have a problem. You might also try and take some weight off the wheel with a jack to make inflating the tire easier.
