My truck is driving me nuts!!! About once a week it will stall. Turn the key and it fires right back up and I'm good to go. I can't seem to put a pattern to the stalling either. About 2/3s of the time it happens when I'm backing out of my driveway but it also happens in drive. Anybody got any clue what's going on.

 

I have an 01 QC 4.7L that sometimes stalls also. It Tend to only do it when i first start it up for the day,and get a little heavy footed with it before it has a chance to warm up.

 

Maybe the Power Steering Pressure Switch is bad? It's suppose to increase the RPM's when the power steering pump is under load or at high speed.

 

mine dies on me when i down shft but yet if i put it in nuteral instead of gearing down to slow downit does do it

 

That makes sense. I have noticed that the frequency of stalling is greater when turning. I'll check it out thanks.
