won't starts when hot

I have a 1990 Toyota pick-up.  When the motor is hot and I shut the truck off, it will not start until the motor cools down.  I replaced the battery and battery wire and clamps.  (I know this isn’t part of the problem but,)  I did a tune replacing everything; plugs, plug wires, cap, rotor, etc.  All I can think left to replace is the starter.  (The truck will start if I get a jump start when it’s hot)  I don’t want to continue the hit and miss process.  Has anyone else had this problem?  Thanks for the help.

Heres the thing. How hot is it? When a motor gets "hot" the metal expands. When this happens, it causes a large amount of friction. Once it cools down,The parts contract(srink)  his is why it will start when cool.You need to find the cause of the over heating.
Low coolent level
Bad thermostat
Bad water pump
Bad raidator
Blockage in the system
All the tune ups in the world wont help. aaaand if occures to much, The motor will eventually die
