Sounds like the charging system isn't working and the battery is running down. User an inexpensive digital voltmeter to measure the battery voltage while the engine is running. It must be between 13.75 and 14.75 volts. If it is low, measure the voltages on the small plugged-in wires and holler back with those numbers.
