Need Help!!!

Description: Over the course of two weeks, dash lights would not light up until after driving about 10 minutes. Then TACH did not work for about two days. Final while starting up last day got a buzzer with no indicator light lit. Tach would not work and after 6 miles I stopped and then made a turn. Car started jerking (like to much gas or not enough) then died after about 1/2 mile. Sat for 20 minutes it started up then went about 5 miles and died totally and would not turn over again. Turn the ignition and it turns but no cranking. Believe it to electrical in nature but I am not a great mechanic. Please advise if possible.

Might want to check the alternator out.
