I have a 91 mustang gt that i daily drive. I went to go crank it up and it started just fine like always and after 30secs of letting it warm up, it just died and wont start again. It cranks and has fuel pressure. Any ideas of what could cause this? Im thinking the coil went bad?

Easy, pull coil wire from the cap, hang on to the end and crank the engine.
You'll know if it's working,
Unless you die, then it don't matter.
Pretty funny to watch but seriously don't do it, you really could die.
just lay the end near metal and look for a spark, factory coils rarely go bad but
the checklist covers this I believe.
First thing on the list iirc is check for codes.
You have to be methodical when you have issues with efi systems, rarely just swapping parts fixes things,
