The only power connection to all three system is the ignition switch. Try wiggling it to try to duplicate the problem. The spring return from start to run may be weak not letting it completely return to the run position after starting.

If it's not power related all three systems are on the CCD data bus. Try disconnecting the negative battery cable a few minutes to reset the bus.
