You have one of the two issues. One being the battery connection is bad or your car is draining power from somewhere called a parasite draw. It stays running long enough till it sucks your power away all the way. This sucks power while car is off. Second is somewhere you have a fuel blockage which isn't allowing car to breath. Is your carb clean?

the best way to diagnose this is with a live data scan. an engine analyzer is hooked up to the obd port and the car is driven. everything the computer is doing is measured, spark, fuel trim etc. you have to find out if you are losing spark or fuel.
