Any applicable trouble codes? How long since a tune-up? When it stalls, have a helper crank it while you check for spark at the plugs. You can carry a spark tester or known good spark plug in the glove box, won't get hot. If spark plug wire is hot, use a glove. Pull spark plug wire loose, place spark tester in boot, ground metal part of tester to metal part of engine, watch for spark engine cranking.

If you have spark everywhere, use a gage and check fuel pressure. Don't let gas spray all over a hot engine, be careful.

Ther may be an intermittent rpm signal?
