4.5L powerstroke in a food truck - long start/hot stall
I have lurked around a good bit, but have a unique situation I was hoping you guys could chime in on.
I have a 2009 workhorse stepvan with a VT275/4.5L powerstroke/Maxxforce5 (probably some other name I don't know). Its joined to an Allison 1000 auto trans.
It has 140k miles. It appears that almost everything is the same as the 6.0 powerstroke so if anyone can help I think its you guys! Long story short, I've built this thing into a pizza food truck in my driveway and was driving it around the other day on one of these insanely hot summer days and it stalled out while leaving a parking lot in the middle of the road. Basically, it just lost power and then sputtered out to a dead stop. It started back up after a long start and then took off like nothing happened. Later that day after idling again in a parking lot, it did the same thing but this time would start up and then stall a few feet later. We let the engine cool completely, then started up and drove home just fine with no issues! It will always start up, but then stall when I assume it has idled a bit and got really hot. It will sound fine, but as soon as we put it in drive and it starts shuttering and creeps along a few feet then stalls.
The truck has always had a very long start (10-20 seconds), but always starts
It has requested several DPF deletes in the last 100 miles
There is an intermittent CEL, but I have struggled to get it to output the code. It has a J1939 interface.
No white smoke, when its not stalling it appears to drive fine, sounds good.. all stalls have followed a short idle in a parking lot
I bought a scan gauge D and have gotten custom gauges from them, but it has not been very helpful, no FICM, no IPR, or most of the things I would find useful here. It does give me ICP readings which are reading in the 400's upon start and the 200's when running, which makes no sense to me.. so I question whether they are really accurate readings or proper gauges.
We are terrified of breaking down with a truck full of food... where would you start trouble shooting this thing?
