Hi,
As far as a power drain, that is a very good possibility. To determine what is happening, we need to do the following.
First, we need to start at the power source, the battery. If possible, remove the battery and take it to a place like Autozone. Have them charge and test the battery for you. They do it free of charge.
If the battery is good, return it to the vehicle. Connect the positive cable first and then the negative. Make certain the terminals are clean and tight.
Since the lights are flickering, we need to check if the alternator is doing its job. Follow this link. All you need is a voltmeter or multimeter.

Get to this point and let me know what you find. If you have additional questions, let me know.
Take care,
Joe
