No Start. HELP!

I parked my '99 528 in front of the store in 117 degree heat and left her running with the A/C on high. 10 minutes later when I came out, she had shut down and would not restart. She turns over fine but no joy. I recently installed a new intake side camshaft position sensor, and I am having issues with the ABS module. After the install of the CPS, when restarted hot with out "priming" the ignition by turning the key to on for a few secs before starting, she would not idle properly. I also had codes for P1421 and P1423, but no indication of other issues. Now it's the next morning, and still no start. My OBD scan tool is at the office so, is it possible I have another CPS failure, or is there a engine protection circuit that would have shut her down and be preventing a restart? It seems to be a no fuel issue, as I do not smell any unburned fuel during the failed starting.

Ok. Update. Definitely not fuel issue as there is adequate fp in the fuel rail.

Not so fast! Spark plugs are dry. Now what? Found the issue with two codes though: little vacuum line under the intake cover was disconected

It was the 20A fuse under the pass side air intake
