My guess is that you have (1) a chronicaly under charged battery, (2) a faulty charging circuit, (3) you use the car too infrequently for the battery to be fully charged, (4) you have a bad or under capacity battery, (5) you have bad connections somewhere between the battery and the radio (6) any or all of the above. The problem is that when the voltage to the radio falls below a critical point the radio cannot hold the presets. The radio may be OK until you start the car. A low voltage during starting the car will wipe out the presets. If the battery is over 4 years old it is highly suspect especially if you don't drive the car often. Check all of the battery cable connections too. Checking ALL of the ground connections would also be a good idea.
