85 f150 won't start sometimes

I have a 1985 ford f150 that just won't start sometimes. I replaced the icm, the coil, the distributor cap, and the ignition switch and it still only starts sometimes. Also it will run when I start it up in the mornings and then when I put it in gear it will start to die and eventually will die and then won't start for quite sometime. Any suggestions?
