Hey all, sorry I haven't responded in a while. Life got hectic and have been running about 4 hours of sleep a night. I haven't had a chance to call ACS yet, hopefully this week. I have a crankshaft position sensor I'm going to replace this week and see how that helps. I have gotten no farther in figuring this one out yet though.

Here's the rub though, it usually only happens when I'm driving. The only time it's happened while I'm in park is if I stop while it's happening. It idles in park just fine.

Hot and cold.

Gotcha, thanks.

I just finished doing that. Pump ran.

Where is the included diagram? What will this tell you about your VP44, other than it is or isn't completely dead?

Yeah, the WTS still comes on briefly. It cranks when its acting up, just doesn't fire. I've been messing with it today. No lose wires, relays are good, alternator is good, fuel pressure is good. Is there a way to test the PSG?

Yeah, it cuts out completely and that's what causes the wts to come on. You can hear it in the video. Okay, I'll look into the relay. I've been chasing wires but haven't found anything loose yet. It wouldn't be the IP would it?

I cropped the video to just show the stalls. I can upload the whole thing. I am getting no codes with my obd2 scanner. I'm monitoring the fuel pressure with a gauge tapped into the fuel rail and had it under the wiper. Whenever it stalls the WTS comes on like I just turned the key on. The ABS and Brake light have been on since I purchased the truck but have never been an issue. https://youtu.be/v1vHygPkOpQ Here is the full length if it helps any. I just cut out all of the in between driving for the shorter video.

My truck started acting up recently. While driving it will stall or die. I have 19 psi fuel pressure, the fuel filter is new, no codes. It starts fine and idles fine, but once I'm driving it will stall out for just a second and come back or completely die. If it dies, then it won't start again for anywhere from hours to days. Any help is appreciated. 99 Dodge Ram 3500 5.9l diesel Here is a video of 6 times it stalled today. https://youtu.be/jkYmQii0C4c
