1998 Isuzu Rodeo - Dies Suddenly But Will Start Right Up Again

I have a 1998 Isuzu Rodeo, V6, 2-wheel (rear) drive. For the past year or so it has been dying on me suddenly while driving. It will start up again in a matter of seconds or minutes sometimes.



Sometimes it happens three times a day, sometimes it doesn’t happen for three months. Because I can’t replicate the problem, my mechanic can’t figure out what’s wrong.



Any ideas?
