1986 Toyota standard pickup 22R motor no spark after reaching normal temp ?
Toyotas have a spark igniter (small module to the right side of fire wall . When they go out they tend to be ok cold amd then shut down when heated up. I'd try that since it's the most common cause to your situation on that vehicle .hope that heleped Good luck
I see a weak ground connection precipitated by expansion and contraction....just be sure the battery is new and the connection to the engine block is solid and happy with 40 amps....sometimes these turn green with corrosion...especially in the rust-belt~
