OK, with the V8 being temporarily sidelined (at least for long trips) by one 
of our infamous Detroit Potholes, I visited Chicago over the weekend to wish 
a certain someone a Happy 45th -- It's always nice when someone is OLDER 
than you are ;-).  Well, an few hours or so into the 5 hour trip, I get what 
feels like an ignition or fuel cutout (nowhere near 4k rpm, btw).  So I just 
kept plugging along at ~3k, but if I lifted the throttle and pushed down 
again she would feel like she was dying and then suddenly grab. Almost like 
the intake plate (under the igloo) was sticking. Hmmm.  I made it the ~300 
miles with a few more stalling incidents where the car would just die and 
I'd pull over on the freeway, let it sit for a few minutes and she'd start 
up again like nothing was wrong. Would idle OK as well.  Anyhow, it got 
worse as I almost reached by destination to where I had to jump the fuel 
pump directly off the battery instead of the additional relayed connection 
at the battery.  Tried new ignition switch and checked engine grounds, but 
the symptoms persisted.  A preliminary check of hoses found nothing obvious. 
Later found ground signal was not making it to the underhood fuel pump 
relay, so I bypassed that for the trip home last night, but the symptoms 
persisted, except she wouldn't idle anymore either then or this  am.  So 
she's parked in the garage right now with the front wheels on ramps.  Spark 
when cranking is strong.  So either intermittent spark, fuel and /or 
possible vacuum leak (always that possibility).  So do these symptoms sound 
familiar?  I was thinking of doing cursory fuel pressure checks, recheck all 
the hoses and then removing the ECU and checking for cracked/broken solder 
joints.

Your help is much appreciated.
