Check the coolant temperature sensor in the heater coolant hard line. This sensor tells the computer if the engine is hot or cold. My car did this a few years ago and this was the problem. To test this next time it doesn't start when it is warmed up, hold the gas to the floor and start the car like it is flooded. You don't have to pump the gas pedal just plant it to the floor. If it starts then it is the sensor. If it doesn't start then it is probable that the starter is worn out. But the sensor is the cheapest first solution. Hope this helps.
