Stalling on first cold start

code 15 help please

I still have a strange problem I can't get rid of. When the car is cold and I start it, it will fire right up and the rpms will drop quickly and stall back out. If I tap the gas a few times, it will run through it. What I can't understand about this is when it does this, the car also loses all preprogrammed radio stations and resets the clock to 0. I have cleaned all the grounds and power connections. I do have a code 15 continious present(power interruption to computer memory or eec keep alive memory test failed) Does anyone have the test for the circutry for this? I'm really starting to draw a blank. It drives me insane to watch the revs come down and the radio flip to am and static. Does anyone know what else is on the same circut as the radio memory hot lead?

I believe that pin 1, black/orange wire to the positive terminal is where I need to check for good connection/continuity. Am I on the right track?
