We installed a rebuilt short block MAXXFORCE 7 V-8 on a bus but it will not restart once it gets hot. Any ideas on what might be causing this problem?

REVISED-
After running the bus for a good while past operating temperature we turn off the bus. It will not start until it cools down again.

High pressure oil rails, stand tubes, branch tubes, or high pressure oil pump.

I don't think a MaxxForce 7 has a high pressure oil pump, rails, etc.
Why yes, the ORIGinal CHARGER is a Fastback

6.0 does, 6.5 not sure. If he is referring to the MAXXForce 7 as the 6.5. We have 2 like that right now that Rush trucks is working on. Something with the fuel pump and harness.
