It did give me an error code after it shuts off it gives the pressure error code. I'm going down to the boat later today to see if, all the filters are clean. I don't think its an impeller because it does push water when it first starts. Thanks Jim I may try and post this in general as well.
I would say check your lint screen on the unit itself under the front bunk. There's a small sheet filter that slides in and out vertically. Also check that your hull valve is fully open, the strainer is cleaned out, and that you don't have just partial flow coming over the side. I've run my AC on the lift a few times while working on it, and if you aren't getting a solid strong stream over the side it could be the issue. I've never had a high pressure shut down though. Try back flushing the air out by putting your dock-hose up against the water discharge port (with the AC off). That can be one way of re-priming the system if you have an air bubble or full air lock in the cooling water system.
Do you actually hear the compressor come on and run or just the fan?
