Can anyone tell me what is wrong withh my car pls?

[migs]

I have a 1989 v6 2.8 fuel inj that shuts down everytime it reaches normal temp and change gears. It wont start after that until later. Ive changed rotor, pick up coil, dist cap,sparkplugs,wires, fuel pump, fuel filter. People tell me its the camshaftsensor, map sensor, crankshaft position sensor but my car doesnt have any of these. The only i havent bought new is fuel pump relay. Ive ran out of ideas on how to fix the car. Pls pls can anyone tell what is wrong with my car. Thanks
