Possibly.  Copy A to B (see instructions, the Mode to use for this has
changed in the past 6 months or so).

Most common reason for this is not properly wiring the injector disable
switches.  Cold Start line MUST be grounded by the one side of the disable
switches when either set is disabled.  If not, it will do exactly as you
described.  To test for this condition, go to high throttle and disable the
primaries.  If engine dies, this is likely the problem. See installation
guide for details and check wiring.
