Claim 10:
11. A system for controlling fuel supply to a plurality of gas turbine engines associated with a hydraulic fracturing system, the system comprising:
a plurality of gas turbine engines associated with a plurality of pumps; and
a controller positioned to control the plurality of gas turbine engines, the controller comprising a memory with computer-readable instructions operable to:
(a) receive an indication when supply pressure of primary fuel to at least one of the plurality of gas turbine engines falls below a set point;
(b) based at least in part on the indication, initiate a timer;
(c) determine that the supply pressure of primary fuel to the least one gas turbine engine remains below the set point when the timer reaches a predetermined end time;
(d) identify at least one of the gas turbine engine of the plurality of gas turbine engines operating on primary fuel with a highest amount of secondary fuel available; and
(e) transfer the gas turbine engine operating on primary fuel with highest amount of secondary fuel available from primary fuel operation to secondary fuel operation.
