Engine cuts off all by itself--???

'88 5.0, 180K miles, has not been driven much at all in the past couple of years, but has been around the neighborhood a few times and occasionally sits idling for ~20 minutes just to keep things circulating.

I drove it about three miles last night, and I had to restart the engine about 40 times.  It would start and die 3 or 4 times, then start and run for a block or two, then die again.  No sputtering, it feels like you just cut the switch off.  It has 1/4-tank of gas, runs fine when it runs, and has no obvious unusual smells.  It has no preference for throttle position either, it died idling or at WFO or anywhere in between. 

Once time I ran it WFO until it was well into 2nd gear without a problem, so I'm thinking the fuel pump's probably OK.  My first suspicion is some kind of corrosion at the computer's electronic connection, since it sat through a two-foot-deep flash flood back in May. 

I'm going to see if it threw any codes tomorrow if it doesn't rain, but does anybody have any other suggestions as to what might be causing this?

Could be corosion/moisture in the computer
computer grounds corosion
TFI
Ignition switch- known to go bad
? water in the tank

Just throwing some stuff out there.  I would definately run codes and see where that points first.

the gas filler neck enters the tank,, thats less than 2' off the ground.

Next I would check fuel presure and beyond that codes like your doing.
