Default Car hard to start after it is warmed up

2002 Honda Accord VP (value package) 4 cylinder. Car starts fine in morning when cold but after driving it for about 20 minutes, stop at store or to buy gas, it is hard to start, maybe three tries. I started to get engine miss fire codes, replaced spark plugs, wires and distributor cap, ran well for a while, but issue continues. Car died on freeway, had it towed to garage and ignition coil was problem. Again, it ran well for awhile, but codes return and car hard to start when warm. It misses when it does turn over, but after a while it returns to a normal idle. I would greatly appreciate any help.

Problem could be a fuel delivery issue; fuel injector or fuel pump. Suggest getting fuel trims; LTFT and STFT w/ obd2 scanner and look for lean/rich trends.

good luck
