Maintenance/Repairs

When I try to start my truck, often the engine does not crank and the truck makes a noise which sounds exactly like static noise on an untuned radio. Ultimately the truck will start, but I have to make anywhere from 2 to 6 attempts before it starts. However, if the truck has been sitting for 3 or more hours, it always starts on the first attempt. Also, sometimes I am out of town for 3 or more weeks - on these occasions I have to disconnect the battery cables otherwise the battery will be dead upon my return (thought I would mention this - not sure if it is related to the ignition problem). Thanks for any help!
