Why does my ford ranger shut off when temperatures get above 75 degrees. My temperature gauge is ok. (Really on the low side)
I have replaced the control module thinking that was the problem but now I am thinking it might be a fuel related problem. After about 20 minutes I feel a hesitation when I push the gas pedal. As long as I am moving in 4th gear there is no problem but when I slow down, the truck seems to lose power and shuts down. After about 10 minutes it will start back up but I have to rev the engine to get it to move, but it will shut down again when I am below 3rd or 4th gear. I have recently replace the thermostat, radiator, and water pump thinking it was overheating. I also replaced the temperature sensor. What is my problem?

Ok first off I need to know if there is spark and fuel when it dies. So if you would get it to die and then take an old spark plug or a philips screwdriver and put it near metal and crank it over and see if there is spark. Let me know what you find and we will take it from there.

Racefan966: It hasn't been hot outside, so the ranger has been running ok. So what scenarios would I be looking at, 1). If have didn't have a spark or 2). If I did have a spark?

Ok not looking for any senarios just what is or isn't happening so we can rule out a few things. What I really think we need to check is the temp sensor once it is warm enough for it to have problems. So when it does get warm enough to act up simply unplug the temp sensor ohm it and then get back to me with the ohm readings and the temp at the time if the engine is warm then I need engine temp if not then air temp is fine.

OK, yesterday it stopped or sputtered again. I checked the spark with a tool a guy brought just for that and it did have a spark. When the truck started after about 5 minutes it was running but it had no power to move. After 5 more minutes I restarted and this time it took off and I drove about 15 miles before I had to stop. It kicked off again. What next?

Ok I forgot to ask is this truck carburated or injected? I figure it is a 2.3 ltr engine.
