Thanks guys - Crank Position Sensor sounds the likely culprit - definitely
not RPM sensitive as all previous occasions have been while coming to a halt
or taking off gently.

The crank position sensor can be temperature sensitive. We got out of the
back country once in a 4.0l Cherokee by packing the area around the CPS with
ice from the beer cooler. Ran just fine that way for several hours.

My fuel pump ... 96' Cherokee, 4.0 ... went intermittent something like you
describe before finally packing it in. I replaced the pump (had it replaced)
and while so doing replaced the CPS and fuel filter as preventive
maintenance. So maybe as the others have suggested, start with the CPS, my
opinion, worth doing anyway.

I would look very hard at the Crankshaft Position Sensor that is mounted
externally next to the flywheel on the left-side of the vehicle when sitting
inside. This gives the master timing information for the entire engine and
when it goes bad, and they do, it causes symptoms like you're experiencing
