I have a 98 Jeep cherokee that had been having trouble starting for a couple of weeks off and on. Then last week it stalled out completely. When I try to start it it cranks over fine starts then runs for like 5 minutes. Then when I try to start it again it won't start. I've sprayed starting fluid in the throttle body and it doesn't help. I've checked plugs/plug wires/distributor cap/rotor and I have also replaced the coil.

You're missing something here between fuel and spark-do below to determine the cause

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor cam and crank sensors- Note: If it doesn't apply disregard it
