Engine dies every morning.

[GM.Chief]

Hey all, I'm new to the board as a member although I've lurked around here for quite a while. We've been having some issues with our '99 F-350 7.3L. This is a new issue to us.
Each morning, when we need to leave the house, the engine dies on us. We drive for about 5-8 minutes at 5 mph to get out of our community (full-time RV'ers in an RV park) prior to accelerating. Now, we often try to let the truck warm up for 5-10 minutes before we leave, but when we don't, as soon as we get out of the community and start accelerating the truck dies. It sounds like its starving for fuel, and once it dies we have to let it stay shut down for several minutes before attempting to restart it. This has never been an issue before for us. If the engine is warm, his doesn't seem to be an issue. I found the block heater cable and plugged it in last night and this morning I left without letting it warm up (running wise) so as to see if that would help fix the problem. Everything ran fine and there were no stalls, so yay! But this feels like a band-aid versus a fix. The weather here has been cool, but not cold and so it seems extremely odd the way it's acting.

I have tested all glow plugs, glow plug relays, the valve cover gaskets are new, the fuel pump is relatively new, and all filters have been changed recently, and the screen inside the fuel tank is new. I don't really know what else to check at this point and am hoping for some advice. Thanks in advance!

I'd think it might be a high pressure oil issue

start by scanning for codes with a device capable of reading manufacturer specific codes

Sorry it's taken so long to get back on here. I appreciate the responses given this far. My cheapy code reader is not enough to check manufacturer specific codes and today the service engine light came in and stayed on, so I'll probably be bringing it in to a shop for a quick scan if nothing else. I only have a few days left before I have to go offshore and I've had no luck in troubleshooting the issue myself. The HPOP is a possibility, but I really hope not with the way this next week is planned out, but if it needs to be replaced, it needs to. I was wondering what y'all's thoughts are on the possibility of it being injector o-rings vs the HPOP. They tend to be fairly cheap and easy to replace and I may very well just do that anyways as I'm at 120,000 miles, but I don't know if that's really worth the time spent at this point.

before even considering repairing this, you need to have those codes scanned. then, depending on what you find there, further testing performed. icp is one parameter you should be viewing wen the problem occurs

Code is coming up as 1212. Indicating a possible icp issue. I can't leave it at the mechanics overnight like they want however as I have some things I need to do during these next couple of days. Is it worth it to just replace the icp? I don't have any of the equipment to properly test it while driving.

i would say yes, its fairly cheap and if it fixes your problem its worth it, if not.. you shouldn't need a new one for a while and i guess the old one was good so you'll have a spare

Thanks, I'll go pick one up in a few minutes then. Looks like a fairly quick/ straightforward replacement job.

let us know if that was the problem.. it could be the IPR from previous posts i've read on here.. just a thought

So far the check engine light is off and seems to be running good, but there's no real way to tell until it gets cold again. It could be an unrelated issue for all I know. Keeping my fingers crossed. And while I didn't think I'd be saying this before midsummer, I'm hoping for another really cold night so I can test it out. Thank you for your help. I'll update the thread if this occurs again or I get a chance to test it out after a cold night.
