1987 Honda Civic Starting issue

I just had timing belt replaced by a mechanic. He also replaced plugs, rotor button, and distributor cap. The plug wires are less than 2 years old and all have spark. Fuel pump is 5 years old. I got stranded then had it towed to him again and he found the fuel filter near the tank was in terrible shape. He replaced it and I had replaced the secondary one as well. Next I drained the gas tank and changed fuel filter again. It will start fine after sitting a long time a day or so. If I have driven 30-50 miles stop and go eat a meal then try to leave the car will turn over and over but will not start. Holding the gas pedal down for 4-5min of turning the engine it catches and just barely runs with pedal on the floor. I have put my hand at the exhaust and smell gas. I have used starting fluid during these times and it does the same thing. It takes from 10 -30minutes to get it going. Once going it runs perfectly idle about 750 no sputter and will not cut off. Even with breather assembly removed while spraying starting fluid it has this same problem of turning but not starting. It seems after it sits for 24-48 it will start. Seems it does this most repeatable after it has been run over a longer distance. I think it is related to the heat of the motor built up from dring ~20-30miles What else can I check? Seems like maybe the air is not right and it is flooding. Another thought I had was the coil is bad but I do not know what the ohm measurements are for the coil and if that could be it since it will run (85 miles most ) well after it gets going no issues. If it was vaccum I think it show up in the performance.
