Battery issues or is it??

so It seem every year i have the same problem and I have no clue to what it could be. I have an 86 supra with a 454. Its seems every time im out and running a while and shut the motor down. When i go to restart it seems like the battery is dead but I will hit the started again and it turns over fine like normal. Battery is new, new resistor, rebuild starter. I cant find any power draw. Do I need a bigger battery or 2 batteries? could I be pulling to many amps when the motor turns over?
