What's wrong with my 02 Cadillac escalade? on 2002 Cadillac Escalade

Yesterday it died while I was driving. When it died I still had power to my radio, lights, ets and my change oil light stayed on. It will start back up with a jump or if it sits for about 5 min. What could it be? I do need an oil change but will that cause my car to shut down? I was on my way to auto zone today to get it scanned but it did on the way and after waiting an hour for the hubby to come give me a boost I just went back home. I'm going to try tomorrow to get it scanned again

Have the charging system (Alternator) output voltage checked, seems that it's not keeping the battery charged.

Alternator was good. Battery wasn't but I bought I new one and it's still not starting.

Have the starter motor checked, 'IF' the engine is not turning when key is turned!!! (IF IT WILL NOT 'CRANK')
