Weird starting problem, only happens on hills

It runs BUT.
One week ago I had a no-start. Checked what I could (harnesses for chaffing, FICM voltage koeo 49.5 and cranking 48, unplugged ICP) without much in the way of tools. Still no-start.
Towed it to a delaership, it sat for a full day. When they unplugged the ICP, it fired right up. The mechanic hooked the truck up and watched what the ICP sensor was reading. He says the readings were "all over the place", so he replaced the sensor. It fired up and ran fine.
I picked it up last Friday, restarted it 2 or 3 times, no problem.
Drove truck on Saturday, early morning start took 15-20 seconds of cranking, then it fired up.
The next 2 restarts were just like before this all started (flat ground).
3 hours later (parked on incline, nose up) no-start.
Rolled the truck down the hill onto flat ground, replaced batteries (failed load test) and it fires in about 15 seconds of cranking.
Every time I park on an incline with the nose higher than the tail, it takes quite a while of cranking to get it going, unless it is restarted rather quickly (within a few minutes). If I park on the flat, even for hours, it restarts fine (or just a little longer, maybe 1 second), unless left for more than say 6 hours. Then it takes about 10 seconds of cranking.
I am thinking it has something to do with an HPOP leak. Perhaps it is allowing the reservoir to drain?
I would figure this to possibly be the STC fitting, but it isn't isolated to hot starts and occurs more on inclines.
Is this possible or am I smoking crack?

What is the fuel level in your tank? Does that make any difference?

this is de-ja vue for me. Mine did the exact same thing on inclines hot or cold. After 4 trips to the dealer, the last 2 via flatbed its running like a top.

The causes were. leaking stc, ipr 3 and 5 injector and finally a failed hpop. After all this the dealer was stumped. The writter claimes he's never seen anything like it.

You're not on crack. It's a hp oil issue.

Fuel level has been full to 1/2 tank. No difference.

When the dealer had it on their computer, I asked them to check everything they could. The service department made it a point to tell me that everything they could monitor looked normal, injectors included.

When the tow bill STARTS @ $250 a whack, I don't want to have to do that too often. The only good shop is on the other side of Queens from where I am, it costs me $35 just for the taxi to go get it. The trip cost me a touch over a thousand bucks just to have my truck scanned and a $200 part replaced, get a pat on the back and shown the door. I could swallow that pill easily if the underlying problem was repaired but it was not.

Find a shop that will air test the hp oil system. You have leaks in that system. It won't be cheap to fix. The injectors I had replaced were bad orings on the oil side causing their failure. I feel your pain.

Still under warrenty? How many miles? It might be cheaper to purchase an extended warrenty,play dumb and have it fixed on Fords dime.
