Anyone know Ford 351, FI no start ideas

[FlintTony]

I sent my 95 Ford E250 , 351 fuel injected van down to Florida. 25,000 miles, sits a lot, run it a few times a year. Guy driving it got 25 miles from destination, van starts to run bad. Acts like no fuel. Change fuel filter. Van sat for an hour while getting filter. Van started up, ran, but a little rough. Drove 20 miles, quits again. Let it set for 30 mins, started back up. My guess would be ignition related or fuel pump. Only thing is, I don't know these modern engines and all the computer junk. I think I'll just send it to the dealership mechanics.
