every 10 minutes alrm goes off for no reason but it is the door trigger is what is setting it off. when alarm is going off domelight is not on and all doors a shut so there is no faulty switch. Is there some type of power or voltage loss on this vehicle if so how do i bypass.

Add a diode to the door input wire. Cathode towards alarm.

Try using a different source for battery power. The red wires off the ignition switch are the best to use. You may ahve tied into a circuit that goes to sleep after ten minutes. Make sure your ground is into the body of the car. Use the blue and blue/white wires at the BCM on the driver's side firewall for your doorpin wires. Just make sure to diode isolate them from each other.
