05 jeep liberty turns off after several seconds

Question

I installed a int-sl+ with a crimestopper rs4-g5. The vehicle starts with the remote and run for anywhere from 5 to 40 seconds then shuts off. It is connected with data link and in tach mode. The LED is on solid while running and turns off when it shuts down. Then the LED on the rs4-g5 blinks slowly untill I turn the key on. Thank you for the help
