This anomaly may be tough to crack.  An incomplete list of usual suspects would include installation, fuel, fuel system, power, mechanical, software, interface, and signals issues.

AEHF-2’s scheduled launch has been unscheduled until the issue is resolved.  Trying to use another vendor’s LAE would create an entirely different set of problems.
