Check the crankshaft position sensor. You may also want to pull
the fault codes. Allegedly on the 96 ZJ you'll need a scan tool,
which a local parts place may be willing to do.

That sounds exactly like the crankshaft position sensor is crapping out.

Hmm.

Well, if your sure it's not the CPS, that leaves a few other options.
A bad ESD relay (Emergency Shutdown) can do this. 9.00 part but can be
easily tested. It's in the relay center behind the battery.

What do the codes tell you?
http://members.cox.net/wilsond/engine_codes.html

Tach hitting zero sounds more like an electrical problem, the
CPS (Cam Position Sensor) located in the distributor might be
your cause.

Other possibilites are loose ground/pos connections, rusted out
engine ground strap, etc.

Start with the codes.
