2000 f450 starting problems, i have to Reset the security system every other day in order to start truck? i have to turn the key to the on position, wait aprox 10 min and turn it off then on to start. it will start after doing this. i need to know what would cause this to happen so often? problem started aprox 8 months ago. use to be every 3 to 4 months, now every week a couple of times. everything else seems to be perfect. i installed a new battery.
thanks
