Welcome to the forums.

Your oil fired furnace has a fan/limit switch that controls the blower in heat mode.
It is explained in this thread.... Lincoln Barriere LBO 105-DR oil furnace questions

If your furnace is shutting down after 3-4 minutes that sounds like it's overheating. That means the fan/limit switch is probably ok and you have a problem with the blower motor.
