Cummins ISL400 runs and quits... questions
I'm currently stuck in a RV campground with a engine that won't run. I called and talked with the nearest Cummins service center and the tech on the phone says he thinks it's the lift pump. The pr...

You sound as if you're doing all the right things.
Your comment about how it acts like it's running out of fuel, could also indicate a bad fuel filter. And don't think just because you may have changed them recently, that it couldn't be that....(unless you JUST changed it).
I've had problems with fuel, that had me changing out the fuel filters daily! I had to flush the tank, to get it back to the normal 300 hours on the filters.
Also, as soon as I's shut down the engine, the fuel gauge would go back to normal, and the engine would start right up again, but within minutes, the fuel gauge would start showing a vacuum, and the engine would start being fuel starved and cut off.
We had growth in the fuel. Be used an algae eliminator (forget the name though), which helped, but as I said, I ended up flushing the tank.
I would think that the lift pump would run, until it reached pressure, and if it did that in 30 seconds, so be it...but I may be wrong there! I've had similar problems with the fuel pump on our Onan Genset, and it would cut out after a few minutes (overheat, I guess, so tripped, and I could restart it a few minutes later). Replacing it made the difference.
Hopefully, you will have the same results....though it's strange that it seemed to be fine, after you "rebooted" with the disconnect of the battery?????
Good Luck:)
