Line Sensor testing

[LV1601]

I think I am over thinking things, but I was testing the line sensors with LabView recently.
I wired all the line sensors properly as according to the manual and other threads on the forum.
Brown 12V red Wago connector on the Power Distribution Board
Blue Black Wago connector on the Power Distribution Board
White into the DI/O of the Sidecar
Black unused

I see all three line sensors giving true and false values and change from green to yellow/orange with the reflective tape is under it. As a test i ran the program on autonomous without the motors to see how they would react. I placed the right sensor over the reflective tape and the jaguars are lighting that they are going forward. The problem is that they will only go forward for like 8 seconds before the program would stop. Is it suppose to do that or do i have a problem.

Can someone please clarify this to me.
