Genie ISD 990 opener Remote model number is ACSCTG Type 3

The door opener is about 3 years old and I have been having trouble for one year. The opener works fine for a week and then will not work at all. The green indicator light is blinking once. To get the opener working again I have to turn the circuit breaker off and on. This method has worked until last week. Now I have to flip the circuit breaker several times and wait a while and it will start working again. Once working I can cycle through 4 or more times before it stops working. This time the green indicator light is blinking 3 times(over heated). Once cooled it works fine for a while and then will not open till I flip the circuit breaker.
