Could be a charging issue (are you making 13-14 volts at 3000 RPMs or higher across the battery? Battery connections? Also could be loose or corroded fuse box clips or damaged fuses. Bad or corroded connectors in any number of places. Loose grounds? Battery could just be a piece of junk...you have no history right? Have it tested or just get a new one and start there. When it is fully charged check for 13.2 to 14.5 volts across battrery at 3000-4000 RPM, then report back and we can try and figure this out.

weak battery on start

I've been having similar problems, slow crank, hard start. If I jump start it, it fire first try.

After much searching I discovered a wire inside the tail light assembly had worn through the insulation creating a current leak. A bit of electrical tape and better routing and problem solved...

Good luck mate!
