It sounds like you are losing ground, please verify that there is a good ground connection to the black wire in the main 6 pin harness.

Ground is very good.  The remote start portion works fine.
Try lowering the firmware to 4.18 and re programming the module.

Also what wire did you hook up the purple/yellow and lt.blue/black to in the vehicle?
Pin 8 Data
what is the wire color?
I pushed the car. Don't remember the color.  But I tested the wires in the connector to locate the  12V, IGN and GND. They were exactly as the pin out in the maunal complete with the empty pins. So the wire I used for Data has to be correct.
Once you have checked let me know.

Can also try the 4.18 and programming see what happens.
