Welcome to the Tahoe forum. Someone here should be able to help.

 

.......also have remote start that has been installed for many years

 

So is it dying after 30 sec with the remote start or 30 sec after using the key?
If its 30 sec after remote start I would look at the conditions needed for remote start..

Is it running smoothly for those 30 sec
Any codes setting
AC off or On

 

got it the remote start shortd burnt up pump 1st
