1989 740GL won't restart after it gets hot

My 1989 740GL 4dr automatic (non turbo) won't restart after it gets hot. This happens after I drive it for 20 minutes or more and then shut it off and leave it. When I come back it will not start. It doesn't crank/turn over. All electrics continue to work. Then, after about 2 hours it will start right up. It seems that having the hood open lessens the downtime needed. It has happened 3 times so far. A mechanic suspects the starter or starter relay but can't reproduce the problem so hasn't tried to fix it. Any ideas???

Distributor pickup. I will try to find writeup.

Were you able to resolve this? I've got the same issue with a 92 940. The car will sometimes not crank after driving until about 30+ minutes after shutdown. The car will always start fine if you attempt to restart immediately after shutdown though.
