This can be a few different things. We will want to get the codes pulled as it could be part of the problem whatever is setting the codes. But most of the times I find the issue to be a unsteady idle because of possible tune up needed or vacuum leak. I also know if the pressure drops or goes about the range it will kick out. 45 is really getting up there could actually be overcharged. Normally they should be around 35-40 range. I have attached a image showing the things that will kick out the compressor.
