Three possibilities that come to mind...
One, your preamp may be passing D.C. This is a bad thing and if it turns out to be the case, it is a good thing your amp has protection circuits since this is a great way to blow things up in a most spectacular and amusing fashion. It is the least likely problem, but potentially the worst. CJ makes a good product, so this is the least likely scenario.
The second potential problem off the top of my head would be a bad output jack with an intermittant ground connection. If you are running the Citation bridged, then it is particularly sensitive to this (Also, if you are running bridged, double check the bridging connectors...if they get knocked loose, the amp will do exactly what you are seeing). Try swapping the interconnect cables you are using and see if that alleviates the problem. You might try some contact cleaner for giggles. I would also check to make sure there isn't a short in the speaker cables that may have been triggered when you moved things around to hook up the CJ.
Third, your new preamp could be overloading the input of the amp...but that would usually only happen at higher volumes. If the amp only shuts down when you start to turn things up...see how long it will run at low volumes. There may be a way to adjust the output gain on the PFR...I'd contact C.J.
