97 Jimmy V6 - 4.3 liter automatic - Engine dies when the weather is hot

[unykron573]

Hello all, I have spent close to 4k in the last 3 months with promises my problem is fixed, then we have a 90 degree day and I go for a drive and the engine dies and won't start until its cooled off. I have had all kinds of sensors, the thermostat , etc replaced and am no closer to having the issue fixed then before I had the parts replaced.

If any of you have any idea or had\ have the same issue I would really appreciate your input. Thank you in advance.

Edit- Forgot to mention on cool days it runs with no problems, only the hot days do I have issues.

I'm sorry, this sounds extremely frustrating. The car just stalls out when it gets warm? No other symptoms? Can you describe more what happens before it stalls?

It doesn't do anything weird or make Any noises, just stalls like as if I turned the key off. Only on hot days though. Cool weather it runs perfect with no problem. After a few hours it will start again and be fine until it does it again.

I'm hoping someone pipes up. The same thing happened to me yesterday in my '96.

Turned out to be the fuel pump on mine.

my 2001 did the same this week, but it start immediately and stall again when push the gas pedale. temp hot ( more than 95). i found that the problem is when the tank is less than half. i fullm the tank and then everything is ok until it comes under half. so i finish my 3000 miles trip fueling befire half tank and no problem. i think de gas come too hot!!!
