Any idea's please? 2000 1500 2wd 5.2 215,000 miles. started a couple months back, every few days driving down the road, as if for a split second the engine was cut off, then everything normal. It is very startling when it does it, noticeable to everyone in the truck. It has progressively gotten more often and now is several times a day. Computer has no codes, stored or pending. Fuel pressure is 47 psi sitting at idle in my drive. Runs perfect the rest of the time. It is original fuel pump and that has been concerning me for a while with the high mileage.
It feels as though I'm waiting for the day it just stops. Want to find it before I'm stranded. Please toss out ideas. I'm desperate.
Thanks
Bob

 

It sounds like a fuel delivery issue to me. Maybe fuel pump, maybe fuel filter? I had a different vehicle with a faulty fuel pressure regulator that was giving me good readings at idle, but when I put a load on it the pressure never changed. I'm sure someone else will probably chime in with a better way of testing, lol.

 

Take a look at the ASD relay, swap it with the wiper relay, and see if the problem goes away.
