**** Check the electrical connections at the pump first. I had a similar
problem - the engine would die while driving.

On my 85 4k, the electrical pump connections were just springy push-on type
of connections. These corrode and/or loosen up and  you get intermittant
operation.
I cleaned the contacts, and the pump electrical posts. Then I put the
electrical contacts back on AND I secured them with brass washers and nuts.
Problem was solved.
