I had the same problem.... Pulled out my old Ford standard distributor (EFI) and replaced it with a shiny billet MSD distributor..... all went well till it warmed up then it would just stop. No fuel pressure when cranking. Then when it cooled down it would get fuel pressure and start again..... I took out the MSD distributor and put the standard ford distributor back in and problem solved..... So I then replaced the MSD internals with the ford internals and put it back in and it runs, even when warmed up ... but..... it misses and runs like a pig when idling around. NOt very nice to drive when you're talking 500 flywheel hp. Soooooo I took it out and put a dirty old standard Ford distributor back in and guess what.... runs like clockwork, no missing etc... Not saying it will fix yours but worth a try... and it did make 383 rwhp with the ford distributor....
