Battery drains while running. Battery will be charged at 100% and after driving the car a couple of minutes the battery drains to 50%. Car continues to run, but after it is turned off it won't start again. Have replaced starter, starter solenoid, battery, battery cables and alternator. What else could it be?

Take the car to a major auto parts chain store like AutoZone, Advanced Auto Parts or O'Riely's and they will check the charging system in the car for free. That is the simplest way to find you problem.

What does your amp meter in the car say when its running? If your battery is very old then it may not be able to hold a charge anymore and may discharge due to heat after driving for a while.
