Truck acting up.

My '86 720 has started to stall.
Stalled twice under load Thurs
night.Then I was cruising at 60
and it stopped running.Both times
it started back up.So I figured it
needed a fuel filter change.Changed it
yesterday.Then my wife moved it and the
it wouldn't start.Primed with gas.First
time started then stalled.Next time started
and ran.Anyone have any ideas?

:thumbsup: Try checking your timing. I had an 88 Ford ranger that would stall for seemingly no reason. My mechanic checked it out and it was just out of time.
