I am not sure but I might have found the problem. It starts with no problem for the last 5 days.

There was a second problem that led me to the first. Sometimes the heater fan did not start properly. I have traced the wires and found that the ground was not tight.

Along with the ground from the fan is a ground to the ECU. Cleaned and tightened them both and everything works for the last 5 days.
