1970 Chevy Chevelle V8 Two Wheel Drive Manual

Hello,
I have have a SB 400 in my 55 chevy.
I can start it fine, but after driving it for as little as 10 mins, I shut it off and then it will not turn over.
It tries to to turn over, but it acts like the battery is dead. The battery is fine and shows that it is fully charged. I thought it was my starter getting to hot from my exhaust pipe, so I wrapped it with a heat shield fabric, but that didn't work.
I can let my engine sit for a while and it will start right up again.
Thanks

What type of ignition system does it have? Converted to HEI?

Do below next time is refuses to start

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
