Why is your dodge ram gen light on and truck lose power while driving?

I am not familiar with your vehicle and thus this answer will be generic in nature and applies to all spark plug using internal combustion engines.
IF the "gen light" [charging system idiot light] is ON, then that indicates that more electricity is being taken out of the battery than the charging system is putting into the battery.
If that's the case, then over time the battery voltage will become less and less. At some point, the voltage to the primary winding inside the ignition coil(s) will get so low that the output [supposed to be very high voltage] to the distributor system and spark plugs will be reduced significantly.
When the voltage of the spark plugs is significantly reduced, then the spark is not "hot" enough to properly ignite the "richer" fuel/air mixture at higher throttle power settings, resulting in "loss of power" and sometimes "missing" [also known as misfiring.
