Is it an indication that something could be wrong?

I agree with "1badaz" about the switch panel. But, before you go throwing parts at it, let me ask you this. When you turn the key to "run" do all of the switch lights flash? Next time the "2 HI" light goes off, stop and turn the key off, then turn it to "run" and see if "all" the lights flash? If the "2 HI" doesn't then it's probably the switch panel other wise you need to get it scanned for trouble codes to really pin point a problem in the system..........Steve
