A system and method pumps process fluid from a cryogenic storage vessel to a vaporizer, and delivers the fluid as a pressurized gas. The method includes measuring process fluid temperature after the process fluid exits the vaporizer, temporarily suspending operation of the pump when the process fluid temperature is below a threshold temperature, and restarting a suspended pump if at least one predefined enabling condition is satisfied and process fluid pressure is less than a high pressure threshold. The system comprises components that cooperate with one another to execute the method, including a storage vessel, a pump, a vaporizer, a conduit for delivering a pressurized gas from the vaporizer to the end user, a pressure sensor and a temperature sensor for measuring process fluid properties within the conduit, and a controller for commanding operation of the pump responsive to temperature and pressure measurements.
