No start when Hot only
This might tie into another thread, the 2003 max has a no start issue when hot only, cold or after it has set for 5-6 hours it's fine.
I'm not too smart on on Maxes but this can't be too difficult.....search didn't come up with much!

Injector return flow excessive when warm. Measure the return flow from each head into a graduated cylinder. This will tell you which bank is the culprit, or both banks.

Kind of what I was thinking in my 12v mind, thanks Glenn, about to post another similar one for a C/R.
