no start when warm

The truck starts fine when cold, but If I drive for more then 30-40+ mins the truck doesn't want to start (05 f-350). It will turn over fine but then quickly sound like the battery is dying. If I let it sit for 20 mins or sometimes little longer it will start back up. I have been doing some research and found out it might be hpop, a quick connect fitting on oil pump, stc fitting which I think might be the quick connect fitting or Icp valve. Is there anything else I could be missing? Also would any of these cause the battery to quickly drain but seems to recharge after cool down. I will but a multimeter on the batter tomorrow and check voltage. Thanks

Sounds like you have a high pressure oil leak. Yes, it could be one if not several of the components you stated. However, I would perform an air leak test to see if you can hear or see where the leak(s) is coming from. IPR valve, oil rail stand pipes, oil rail plugs, HPOP, stc fitting, injector o-rings, oil rail o-rings. Were you planning on replacing all the components of the high pressure oil system? That can get a little pricey. As far as the battery drain goes, that just sounds like weak batteries. I don't think there is a connection between the batteries and high pressure oil leak. Also, make sure you perform a load test to check the cranking amps of the batteries not just voltage. Can you get a hold of a scan tool to check what the ICP is reading when the it doesn't wanna start? Needs 500psi to fire the injectors.
