Mine has gotten to the point that it won't even start when warm. Nearly had it towed last week when I shut it down to fill up with gas. By the time the tow truck arrived it started and I was able to drive home. Fires up great cold, runs great, but if I turn it off and try to restart hot I can just crank away till the battery is nearly dead.
My original 1938 ford flathead does that same thing. I've been told it's caused by a bad coil that fails when it gets hot.
