You probably want to look into a couple of 14+ amp hour lithium ion motorcycle batteries. Probably a little less than 2 pounds each and they hold up real good. Use one for hot laps and heat, then put the fresh one in for the main.
The problem is you are powering a fuel pump, ignition system, and injection system on a total loss electrical system, and when the battery gets below 12 volts those electronics go crazy.
Some smart guy is going to look at the little generators used on John deer lawn tractors and put a timing belt pulley on one of them and drive it off the engine timing belt or maybe off the PS pump. Then you will be able to get by with one battery.
