When you use your scan-tool are you looking at the screen that shows the readiness status of the different fields? If there is an area that shows a failure to complete initiation, what is this failure in (EVAP, 02, ).
Also back in 2002 what did you have done that cost $1000.00?
What I gather is that your suv has an active code and when you reset the ECU the light stays off while the ECU is in default. And then when it comes buck on-line the light returns.
If your scan-tool isn't picking up an engine code while the light is on then the code is dealer specific. Generic scan-tools are a great tool but they will only pick-up generic codes.

Ok you most likely will not like me at all -but - here goes. The one thing none of the readers or test can pick up are bad cam lobes. If the cam is not adjusted right and you have hydrolyic lifters you will get this problem and the car will still ring great. My guess is you recognise there has been some power loss but thevehicle has so much power it just breezes through the power curve and you don't think about it until inspection time.
I am sure this is far from what you want to hear but I say - take the vin - and check for RECALLS - they get lost in the mail or some such. You do not have to have bought the vehicle new to get RECALLS fixed free. Because of your problem -please also ask about Service Bulletins as they sometimes address things like a sneaky exhaust gas problem. As an easier thing to check I would look close at the o2 sensors and all connections should be pulled and replugged. Sometimes with electronic - tight isn't good. I am a retired Rolls Royce mechanic from Palm Beach Motors and I can tell you - Tight in electronics is not always good. Check the connections by pulling them and re-plug them Fuses too.
