Shut off while driving now it turns over like it wants to start but does not start

Hi, My battery is now dead from trying to get it started. The list of things I have fixed already are as follows: fuel pump, did a tune up, harmonic balancer, all the stuff behind the harmonic balancer, crank shaft sensor, coils for spark plugs and it does have gas in it.
It all started while I was driving and while on the highway it slowed me down and came to a stop on the side of the road and left me stranded there. Still can’t figure out what is wrong with it. Help me please. As this is my only transportation I have right now. Thank you in advance for your help.
