Assume you will check all your battery connections.
Since you could start the engine by using the boost solenoid switch the problem is not your boost solenoid but it may not be getting activated when the engine is running.
One way to check the boost solenoid is to start engine and see if the chassis batteries are getting voltage from the regulator. They probably are not. Then have someone hold the boost switch and check voltage again. If you have alternator voltage at the chassis batteries then the oil pressure switch is probably bad or perhaps not connected.
If you don't see alternator voltage on the chassis batteries with either of the above then suspect your alternator.
The boost switch and the oil pressure switch ground the boost solenoid coil so if you have a bad pressure switch you can run a temporary ground to the boost solenoid coil while you are running the engine.
