A scope could check any fast changes in the battery voltage only then you can be sure if that is a problem or not.
And yes any caps should be in the power part of the system like in the power lead to it
Another strange thing is that part of the the program keeps running.
A full "freeze" of the "computer" would leave the solenoid either open or closed. Either of these states would stop the engine (by flooding or starving of fuel)
Unless i misunderstand the problem this appears not to happen .
