I know it's been a while,but I said I would post the answer when I found it. It finally got hot enough to test again today. Letting it idle in the heat, it no longer over heats and the coolant never got above 95 C/ 203 F. So the radiator cap solved that issue. The gauges still stopped...

It was hot again today, so got to test the radiator cap. Definite improvement. The jeep did not overheat idling, but the temp did continue to climb and not level off. It got to 93 C. The IAT got to 73 C and the mirror read 31 C. It was about 27 C outside air temp. The gauges cut out at 74...

Small update. As stated earlier, I'm going item by item as I want to know exactly what the issue is instead of doing it all at once and having no idea. So in that vein, I replaced the radiator cap today. It was warm out, but on the edge of when it would overheat in traffic before. It seems...

After running it on a hot day with my OBDII connected, it is overheating at idle. So, the gauges dying are a symptom. Weird that happens though. Not sure if I also have a crank or cam shaft sensor that doesn't like the heat. Jeep runs fine even when over heating though. So, now onto the...

Thanks for all the suggestions. I'll trace some wires this weekend to eliminate some potential problems. I installed the grill inserts over winter and it has only just started getting hot, so something could have failed in that time. But as always, look at what you just did. I did a fair...

As stated, everything works fine until it's over 80 f outside and the engine bay temps get high. Next day forecast for that is Monday here, so I'll have to wait until then to test it out. But that is the plan to test the relay, or eliminate it.

I have done the cluster self test. All good there, everything works as should. I had a look at the grounds and nothing obvious yet, no loose connections or corrosion. I know that doesn't mean they are good, but I don't want to do too much at once. I want to know for sure I found the problem...

@hear, It's the SKIM light, my bad. I've got ASD stuck in my head from all the research.

Thanks, macleanflood. Battery terminals are pristine and tight. First thing I checked the first time it happened. Battery should be fine. No issues starting normally and cranks over quick, even when it won't stay running. I'll do the cluster self test tomorrow when it's cooler. I'll check...

Been reading stuff here for a long time, but first post. I have an 03 TJ Sahara (Renegade), New Zealand export, as I'm in NZ. It is a 4.0L, 5 speed and is right hand drive. So here is my problem. The last couple of weeks we have had some hot days, (summer here, sorry) and when it gets over...
