Hello and welcome! My name is ***** ***** I can assist you with your question. How does the engine run other than the stalling condition? Does it have plenty of power under a load? Does it idle Ok or does the idle fluctuate when coming to a stop?

Customer: replied 10 months ago.
It seems to run fine. Although having said that mt gas gage was crazy the other day? 1 day alst week it ran a little week and would not get above 3500 RPMs on highway,uphill with a trailer on
Customer: replied 10 months ago.
It seems to Idle fine I let it run the other day when it stalled 10 times for 30 mins and never stalled
Customer: replied 10 months ago.
It has stalled with full tank and partial tank as well
Expert:  AMEDEE replied 10 months ago.

Does it always start right back up after it stalls out?

Customer: replied 10 months ago.
Longest time in between stalling and starting has been 5 mins
Expert:  AMEDEE replied 10 months ago.

So it just cranks over but does not start correct?

Customer: replied 10 months ago.
Correct
Expert:  AMEDEE replied 10 months ago.

Have you checked the fuel pressure or the fuel pressure regulator?

Customer: replied 10 months ago.
I Have not I am very mechanically inclined but have never done either test before
Expert:  AMEDEE replied 10 months ago.

Ok, the reason I ask because this is one of the most common causes of a stalling condition and it is very easy to check. The fuel pressure regulator is located under the hood on the fuel rail. There is a vacuum line going to it. Remove the vacuum line or hose from the regulator and see if there is any fuel in the hose/line. If so, the diaphram inside the regulator has ruptured and the regulator will need to be replaced.

Expert:  AMEDEE replied 10 months ago.

If you were to get a fuel pressure gauge hooked up to the fuel system, then you would see the fuel pressure drop after turning off the engine. It should hold nice and steady after the engine is turned off. If not, something is leaking fuel

I am heading to the shop shortly to which I can check then.However this problem 1st started a month ago stopped for a while and just started again. A meachanic looked at it drove it and it never didi it to him . I drove it home apprx 10-12 miles and it stalled around the corner from my house.
Expert:  AMEDEE replied 10 months ago.

Some other possible causes would be an air/vacuum leak, bad mass air flow sensor or even a bad/lazy idle air control motor.

Expert:  AMEDEE replied 10 months ago.

The regulator will look something like this..

Expert:  AMEDEE replied 10 months ago.

Now if this is not leaking, I would suspect some of those other things I mentioned.. but be sure to check the regulator for leaks first.
