Does not start after warmed up

The car starts starts and runs fine, but if I turn it off and try to restart about 45 minutes later it doesn't crank and of course won't start. After it cools, another 20 minutes or so, it starts and runs normally. If I try to restart sooner, right away, after only 10 minutes, or whatever, it restarts and runs fine also. A simple example; If I drive it to the grocery store and and come back out to go home, it won't start immediately. But if I drive to a restaurant, sit down enjoy a meal and then get back in the car again, it starts.
A check of the codes indicates a failed crank position sensor, but it doesn't show any other symptoms of this problem that I read about. The part (Part Number: 22053AA020) is discontinued. I have not been able to locate a used one. I would love to find a clever work around.

Any, any suggestion short of giving up on my beautiful cult classic is greatly appreciated.
