04 cobra, ~200k miles. Sometimes when I key off the car the gauges will start to sweep to zero but freeze and the odometer will flash dashes (which I think means it lost connection with PCM). At the same time when this started happening, every month or two (i.e., very infrequently) when I try to start the car I"ll hear a loud CLICK and then I'll lose all power to the car (everywhere, for example, no power windows or trunk, etc...). If I pull the key out of the ignition I hear a loud TICK TICK TICK coming from underneath the driver dash. If I stick the key back in the TICKing will stop, and resume if I remove the key. The only way I can get power back to the car is to disconnect the battery, wait a minute, then hook it back up. Then everything works perfectly, at least until it happens again. I kinda think CCRM because of the odometer flashing dashes at me, but I don't think the CCRM would explain losing all power in the car when I try to start it. I kinda think something with the starter, like maybe it's shorting itself and that causes a circuit breaker to blow, but then it should be a consistent problem, not one that happens every month or two.
