Morning, I found your problem...its going to be your fuel pump. Allow me to explain. When you start your car in the morning the car starts just fine. As your driving the fuel pump will eventually get hot. Therefore the circuit cuts off when you turn off for a while then you jump back in to restart the vehicle and it doesn't. The reason is when the fuel pump gets hot it shuts off due to circuit wire inside the pump.
You can almost say like overheating. Therefore your pump is going out. Replaced 7-10 of them in my time as a mechanic. Do yourself a big favor. Don't get a used on or Autozone. Pep boys or Napa will do just fine. Goodluck.

I WOULD CHECK THE DISTRIBUTOR FOR PLAY ON THE SHAFT, ALSO CHECK THE IGNITION ROTOR AND DISTRIBUTOR CAP INSIDE FOR CORROSION, CHECK THE WIRE , ( SPARK PLUGS ) WIRE, CHECK THE CONNECTION INTO THE CAP. WHEN STARTS TO SKIP IS THERE ANY WAY YOU CAN CHECK THE SPARK, IF IT DOES NOT SKIP, CHECK THE SPARK ANY WAYS, SHOULD BE WITH OUT A DOUBT BLUE, NO YELLOW OR ORANGE IS NO GOOD, BLUE. LET US KNOW.

Car starts hard when hot out


the Mass Airflow Sensor may be dirty. lightly spritz with cleaner(throttle and intake from CRC), let dry completely, 30min, then reassemble. by the way, air filters can get dirty enough to choke an engine make sure to change evey 8-12K miles or yearly.

Did you change spark plugs wires? fuel filter? I do not know if your car has MAF sensor, but if it does, clean it. Use CRC- Mass Air Flow Sensor cleaner. also check Spark Plugs Gap and coil (s)
