1990 2.3 no start when hot

We just bought a 1990 Ranger with a dual plug 2.3, manual trans. Truck has documented about 85,000 mi. P.O. forgot to tell us it is very difficult to impossible to restart it when it is hot. You can drive it 10 minutes or more and it won't start. Temp is fine, coolant and oil levels are good. Cranks fine, but no fire. What is everybody's experience with this? Thanks in advance.

I would start by looking for fuel pressure and spark during one of these failure events.

Checked a couple plugs - flooding. Didn't check for spark as no one to turn the key while I watched.
