Sony CDX-F7700 woes...

[asharp1]

I have a Sony CDX-F7700 head unit, Alpine multichannel amp, two JBL 6x9 coaxial and two JBL 5 1/2" coaxial speakers, that sound great, except for one problem. After about an hour of running, the head unit quits palying, and the amp shuts down. After taking off the removable faceplate on the head unit, the back of the faceplate feels extremely hot. The amp os cool to the touch, all connections are nice and tight, and if left alone, the unit will come back on by itself. I assume it cools down to the point of resetting itself. The display on the head unit never goes off, only the sound. The indicator light on the amp goes off, when this happens, then comes back on after the head unit has cooled down. I followed all of the instructions about supplying power to both, have checlked all of the grounds for shorts, as well as the speakers, individually. Its REALLY getting on my nerves. It is installed in a utility van, used for work. The van rides a little rough and I thought that maybe the faceplate was "bouncing" on the contacts of the head unit, so I wedged some paper between the faceplate and frame to see if that is what it was, but the faceplate held steady, and still got hot. What's up with this thing??? I've never owned a head unit with a "removable faceplate" before, and it is very disturbing. Please help, if you can... Thanks in advance....
