The dash lights do stay on when it stalls. Thus, the ignition switch has been eliminated.
Is it possible for the primary oxygen sensor to be at fault? I am now considering the main relay but it does not seem to be temperature sensitive. The car does not seem to be a problem with starting - not even in very hot temperatures.
The problem has persists for about 4-5 months now and it is getting worse - stalling more and more. It occurred after the fuel injectors were cleaned by valvoline.
1 mechanic is absolutely certain it is the 02 sensor; another is absolutely certain it is the fuel pump; and another is certain it is the main relay.
