Check the thermal overload sensor as well. If the unit is getting too hot due to restricted airflow or a dirty fuel nozzle your hi temp switch may be triggering. When the unit shuts off, ohm the sensor to see if it is tripped. You can cool the sensor by blowing on it or for testing purposes jumper the switch momentarily to see if it starts. If it does, your unit is either getting too hot or the switch is going bad.
Some people claim their heaters work ok with the covers off...a sign that they arent getting enough air or their high limit sensors get less heat build up.
Once again.....good luck and be careful.

My draper diesel space heater run for 1 min than go out
Check the flame sensor and clean it if it is sooty or contaminated.
Good luck and be careful!
