I’ve read the TM’s and did a bunch of searches but haven’t found anything quite like my issue.
A little background first, to start with it's a M1009 with no modifications except that I’ve replaced the OEM fuel filter with a spin on unit. The glow plugs were replaced with AC60G’s about 6 months ago to try and help it start better. The temperatures here have been between 70-100 degrees.
To start it in the morning or after work, hit the key, let it spin 3-4 times, back key off and wait for the ‘wait’ light to go off. Once the “wait” light is off, hit the key again and it will start in 2-3 seconds. There is no smoke thru this cycle. Once running, the plugs will cycle 3 times. Normal.
If you run it for awhile then shut it off. If you restart it in less than 10 minutes it’ll pop right off. No “wait” light, no need to crank for a bit. Here’s the problem….. If it sits for much longer than that it needs to be cranked and cranked and cranked. I do take breaks on the starter. There’s no “wait” light. When it does start, there is no smoke and the plugs do not cycle. Once running it just sits there and purrs. I had someone with me once so I had them hit the key after I pulled the pink wire off of the IP pump and it did click when I put it back on. I replaced the fuel filter thinking that maybe the other one was getting plugged. I’ve had the unit less than a year and a plugged filter wouldn’t have surprised me. But that made no difference. I've looked but haven't found any fuel leaks. Nothing around the IP either.
It runs fine. There isn’t any smoke or any kind of hesitations/surges going down the road. I’m thinking a weak lift pump and just putting in an electric pump and hoping that would solve the issue. But I thought I’d ask others who may have a better idea.
Thanks for any help!!

I looked again at everything when it was "warm". I noticed that the rubber fuel line I had ran behind the rear battery looked "a little flat" and it was also a bit soft. Hadn't seen that before, had always been looking for wet spots. I'm thinking that when it's warm it flattens out completely. So, I bought some 3/8 steel brake line, it slid snuggly into the rubber hose, and made a 180 to the filter. Before install, ran a bunch of diesel thru it to "clean it" and then clamped it in good. Last night I drove it for about a 1/2 hour then let is sit for 30 minutes in 75 degree weather. It then popped off after about 3 seconds of cranking. I'm HOPING, that it was the issue, but am still thinking about getting some work done to the lift pump and IP.
