Car Died, Im Stumped Options

[pepsiman]

On my way home I rolled up to a stop sign and when I could I started to pull out. As I let the clutch out, the car acted like I killed it, but when I went to start it back up it acted almost like the battery had been disconnected. Nothing would come on like it had no battery. Power finally returned and my clock and radio had both reset. When everything finally decided to come back on it started right up and ran perfect the rest of the way home. I did a quick look over on the side of the road and my terminals where attached good and fuses where fine. Any ideas on what happened or where to start looking tomorrow?

car messed up again today. on my way to sub way the radio would go off then come back on a few seconds later. this may or may not be related to the engine problems, but it has never done that before. car otherwise runs fine to subway and when i tried starting the car after leaving subway it would not start. completely dead, radio, clock, gauges, everything dead like no battery was in the car. then all this stuff would come back on but when i turned the key to start it would just click, like the starter was going bad. sometimes my gauges and everything else would go blank again and then begin working again. I unhooked the "-" terminal for a few seconds to let the ecu reset and when I hooked it back up car started and ran perfect. Does this point to the ecu? Do they go "bad"?

To be honest, i haven't given the wiring harness a thorough look over but I did look at it and seen nothing obvious. I dont think it would be the alternator since the battery seems to be charged fine and when it is allowed to it starts the car fine and does so quickly. I also ruled out the clutch start safety switch. I tried to start the car with it out and with it in and there was two different reactions from the car, so that is working properly.
