How are you determining that it has spark and fuel? Fuel pump should buzz and shut off when pressure is up to snuff - if it just stays on the pressure is too low.
The common items in these cars are the ign module on the distributor and the fuel pump relay which is unmarked but has the green harness connector and hides under a plastic shield on driver's side inner fender. You can just bend the whole bracket up or remove it with 5/16 or 8mm socket. They are fastened in in a funky way so use a small flat head screwdriver and remember many connector bails on Fords you push to release where they look like you would lift to release,

Let's face it this car is about 22 years old and is an open book of possible problems. I own three of these right now myself and have been thru about anything these cars can throw at you and get surprised sometimes.
I have not had one yet that didn't run because of a TPS or Temp sensor. Run poorly perhaps but still ran. Neither are that expensive and though I don't like to just toss out parts at random at this point it might be worth the try.
Another thing that has never happened with these engines (may just be my own rare experience) is that they have not eaten or jumped timing chains even with nasty high miles.
A real possibility is water in the fuel. The fuel filter should stop it but who knows? I'd just up and replace that fuel filter with the best one you can find. Add some isopropyl alcohol type dry gas and start doing that with some regularity as water is in there from just condensation over the years and this type of dry gas claims to mix with water and allow it to be burned thru the system thus eliminating it. It would be nice to rule this out.
These cars are fuel fussy. They don't seem to respond well to priming or starting fluid and I don't really know why. They also have a feature that shuts down the fuel pump intended to do that in case of a collision the fuel wouldn't just keep pouring out of a smashed car. The reset for this is in the trunk with a red button near left side trunk hinge. If just a two wire connector it can be jumped and defeat the system but NEVER leave one that way. Just for testing only and I don't really think that's it anyway right now.
I'm just tossing out thoughts right now but consider the EGR valve too. If it leaked badly or stuck it could stop the show. They are a bit expensive to replace without good knowledge that they are in fact bad. So far I have had one go bad but not stop the car from running. I have had mixed luck at cleaning out the pintle in them but that was just for small imperfections and not a no-start problem.
Word has it but hasn't done it to me is the pick up coil in distributor can fail - none yet with me and I would expect NO spark if it failed.
Things that don't like heat are.... coil, ign module. The relays in the mentioned box can partially fail. I believe the one with brown connector can stop the car or make it run poorly. They make universal replacement relays I think part # is AR-242 that will fit any of them. Origs will only fit by color coded skirting but I believe they are the same spec relay otherwise and don't know why they aren't interchangable as newer Fords did and many have been fixed with emergency calls to me from broken down customers telling them to put the clearly marked A/C relay in one of two others to get them home and worked all but one time when for some unknown reason a car needed two relays at once for still an unkown reason.
Keep at it. If this car is in decent shape you can get lots of life out of these. Rust has been the killer of all of them before mechanical problems for me,

Thanks for posting the fix. It was my parts guys that said they had a run of problems like that and what you did fixed it. I carry a whole spare distributor that is known working as it can be replaced on the side of the road with just the 1/2 inch bolt in little time and I can make it back to home/shop to finish the repair but of course since I carry one it has never happened,
