My 201Dodge avenger shuts off after 10 seconds when I start it with remote start

Hello, your vehicle's processor is looking for certain things to be in place for the vehicle to stay running unattended. For example, if the car thinks a door is open and the key is not present, then it may shut off. If it thinks someone has tried to shift the gear, it will shut off. You'll have to have some diagnostic testing performed to see what is going on.
