Hi my problem is with my wifes truck, she drives the truck about 35 miles to work, with no problems,
the outside temperature is about 70 deg in the morning, when she drives home in the afternoon, the temp is about 100-110 deg. The truck will lose power and the engine will run just long enough for her to get onto the shoulder, after a few mins it will restart.
it will do this 3or 4 times on the trip home.
i thought it was a problem with the fuel pump and filter so changed that, also replaced the gas cap.
made no difference. There are no error codes.
Any help would be appreciated
thanks Mike

Mike:
Is there any overheating problems? Have you checked the catalytic converter to make sure it isn't plugged? Finally, when this happens, have you ever been able to check fuel pump pressure and spark to the engine?

Let me know.

Hi Jacobandnickolas
i havent been present when the truck has this problem, I will have acess to a presure guage over the weekend and will take the truck out myself, havent checked the spark but I am planning on taking it to a muffler shop on Monday to get the exhaust pressure checked, I changed the fuel pump relay yesterday, and tapped on the cat converter with a rubber hammer, couldnt hear anything rattling around in there, havent drove it yet since changing the relay, I will let you know if theres any change
thanks for your help

sorry I forgot to say there are no overheating problems, but I still find it strange that it only does it during the hotest time of the day?

Hi Joe
the relay didnt cure the problem
the cat converter checked out ok,
i changed the throttle position sensor as i
noticed the engine speed would sometimes rise when the truck was idling.
The problem has not occured since, (the past 3 days)
so im hoping thats was it.
Thanks for all your help
and maybe this will help others with the same problem.

Yes, it will be helpful and thanks for the info.

I will keep my fingers crossed hoping that takes care of the problem. If it changes, let me know and we'll figure it out one way or another.

Hi Joe
the truck has been running good since my last post, but the weather was cooler 80-90 deg.
Yesterday it was 103 deg. The truck cut out, just like before. It refused to start, I brought it home on a wrecker, probably took 1 1/2 hours. Turned the key when it was unloded and it started right up
where do I go from here? The coil is right behind the radiator, can a coil act like this if its too hot?

That isn't good. I don't know if I asked this before, but are you getting both spark and fuel to the engine when it refuses to start?
