CHRT5 '09 Jeep Liberty turns off in 10mins of less after remote start active

Question

CHRT5 remote start. Purchased and programmed by factory Fortin Dealer Mobile Accessories in Scotia, NY USA warmcarnow.com. August 26th 2018  Installed by me following youtube video instructions early September 2018

Lock x3 on factory key. Installed into 2009 Jeep Liberty. Automatic trans.
Has been working as it should up until about 2 weeks ago.

The Jeep starts up fine, then in less than 10 minutes of idle time shuts off by itself while parked and no-one has touched the pedal or ignition, entered the vehicle, or touched the buttons on the fob.

Answer 1

How long did it run up until the 2 weeks ago mentioned in your question?
