1996 Jeep Cherokee promblem starting

When the problem occurs, have a helper crank it while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Don't let gas spray all over a hot engine.

To check for spark, you can carry a known good spark plug or spark tester in the glove box, it won't get hot. Pull a plug wire, stick plug/tester in the boot, ground metal part to metal part of engine, engine cranking, watch for spark. Any applicable trouble codes?
