Crank/no start when hot

Starts no problem when cold, and runs great for hours. Shut off and try to start, cranks but no start. has fuel pressure, spray starting fuel in intake, nothing. has no spark off of coil! Hope you can help. didn't what to go and buy a PCM yet!   

5.0 1998 Jeep Grand Cherokee, pressure will cranking.

Istr these need both cam & crank position signals to start but once running use only the crank so cam sensor droppinh out due to hear soak where to start looking.

When did they make a 5.0 liter keep? I know the 4.0 3.7 4.7 and the 318

This looks like the issue, Thanks. Would it have no spark if the cam sensor was faulty?

I will let you know. Thanks

last few days have been cool in northern IL, so jeep has been running fine. Finally stopped starting again to test cam sensor. This is what I got:
-5v at supply w/ignition on
-5v at signal w/ignition on
-have 12v at ground when ground to + on battery
-have continuity on ground w/ignition on
-no continuity on ground w/ignition off

This is a cam sensor located in the distributor.
I'm bad, it is a 5.2 liter

Don"t know if this went through earlier, didn't see it in the Forum.
