My son's RX7 will start with a boost and after driving for 5 minutes will start right up after he shuts it off. But after he shuts it off again, it won't start. He thought it was a starter problem and got his rebuilt but the same thing is happening. Battery posts and connections look good. Sounds like a wiring problem but am wondering what other possibilites therecould be

Do you
have the same problem?

Connections looking good are diferent than testing good. Try running a jumper cable from the pos term to the fat lug on the starter and adding a ground from bat neg to the engine block

What is the battery capacity. Yu mentioned newer, that means it is not new? Get the battery tested.
