Hi there. From the description you have provided, it leads me to believe there is a charging system problem. Apparently, the battery is being run down while driving. A good battery will recover on its own when it sits overnight. This would account for not having to jump start in the morning. Your replacing the alternator twice leads me to believe that there is an electrical problem to the alternator or from the alternator to the battery.
Circuit tests need to be performed to properly diagnose why the alternator is not working. The engine RPM issues when you start your vehicle in the morning needs to be properly diagnosed. It could be vacuum leaks, throttle plate sticking, idle air control valve fault, among other possibilities.
