If it was an 86 gl-10 turbo, it could have been any number of things to cause it to suddenly not start when warm.
1. Distributor electronics just gave up the ghost
2. Black fusible link wire just broke through completely
3. Ignition switch on steering column finally went out
4. Capacitor wired to coil just went out
5. Hot wire to alternator just broke from being overheated
6. Driver side timing belt broke
7. Disconnected hose from camtower cover
8. Fuel pump just went out
Obviously, narrowing the problem down to either fuel or the electrical spark, will cut your work down. You could pull a plug while keeping the plug wire on, then hold the tip in contact with the engine metal to ground it. Then have someone else attempt to start the engine, while you look for a spark. No spark = electrical problem. Since your starter turns, then it would not be item 2.
