ok
i had a very simmilar problem and couldnt figure it out for the life of me. took 2 weeks.. its my DD too.. ugh luckily i had my motorcycle..

it ended up being my coil. i had an MSD blaster coil that was only a year old. it still gave spark but i guess it wasnt strong enough. swapped it out to a stock one and it ran mint.

when i touched the gas lightly it would slowly rise in rpm but if i gave it alot it would just cut out and pop out the exhaust and die. it idled like crap too and wouldnt stay running for long either (used lots of carb spray lol)

i thought it was fuel for a while but its not that (i replaced the filter and the pump) changed the ignition control module on the dizzy too and it wasnt that either.. (took it off and returned it lol)

find a buddy w/ a 5.0 and swap coils to see if it helps

possible fuel pump or ful pump relay check your fuel pressure and voltage at fuel pump also check inertia switch in trunk but if i'm tellin you this you probably don't know how
