Hi, my name is***** will be assisting you.

This sounds like the battery voltage is low and not kicking the starter bendix up into the flywheel far enough to engage and turn the engine over. The first thing that I would do is check the battery that supplies power to the unit for starting. The best way to check it is a load test so that you can tell what the battery voltage is under a load, if it is dropping below 8 volts under a load then the battery is going to be a problem.
