Claim 0:
1. A method of controlling fuel supply to two or more gas turbine engines associated with a hydraulic fracturing system, the method comprising:
(a) receiving an indication that supply pressure of primary fuel to at least one of the two or more gas turbine engines falls below a set point;
(b) based at least in part on the signal:
initiating a timer; and
increasing a data sampling rate associated with the two or more gas turbine engines;

(c) determining that the supply pressure of primary fuel to the at least one of the two or more gas turbine engines remains below the set point;
(d) identifying a gas turbine engine of the two or more gas turbine engines that operates on primary fuel and which has a highest amount of secondary fuel available; and
(e) causing supply of secondary fuel to the identified gas turbine engine in place of at least some of the primary fuel supplied to the identified gas turbine engine.
