    It is not your pressure switch, that is the first safety control , that will bring on furnace . Not to sure if this is a in shot burner system ? Sounds like there is a temp limit tripping out . Do you have good air flow ? How old is this system , You may have a damage heater cell ? When the system is running try to find out the safety that is open up. Hopefully this will help you out.
