Problem solved! Well sort of. I have found that my memory output (car source) was some how causing the unit to shut off of a half second when I would step on the brake or open my door. I guess the memory input is just as important as the ignition. sense. input. If both leads are not good quality pwr source, then you'll have problems. For now I'm just running ign. sense and memory together until I can find another source for my memory. I may just run a lead to the battery. The only problem I have with running both wires together is the player shuts off suddenly and I get a pop through the amp. But it's better than the player shutting off every time some one gets in the car or I step on the brakes.
