1998 jeep Cherokee sport. Help

Hey guys I need some help. About 2 minutes after I start up my jeep it has no Power it barely stays running. It lasts for about a minute or less and after that everything is good. I have replaced the fuel pump, tps, cps, spark plugs and wires. All those parts have been replaced in the last 5 months. This problem started happening about 2 weeks ago. Any help is appreciated. I drive a 1998 jeep Cherokee 4.0 5 speed

try getting your battery and alternator checked. a lot of places will do it for free. i had similar symptoms on my WJ. ended up being a bad battery.

I just got my alternator rebuilt to 190 amp. I am supposed to put a bigger power wire on it and I haven't yet. Could it be that? And he checked my battery right away he said it should be good till fall.

Close to where I live there's a guy that rebuilds starters and alternators for a living. He had built a jeep Cherokee alternator before to 190 amp for a guy that was doing sound competitions with 8 12" subs. He changed the case on it to a little bigger one and changed a bunch of internals. Not sure what all. But he did a good job

Are the parts OEM? also check and clean your IAC and throttle body.

Definately have your alternator and the battery checked by a third party

He tested it and showed. But what I'm wondering is why does it only do it like a minute or two after I start it up? And only lasts less than a minute

How long do injectors usually last? My jeep had 260,000 kilometers and it's starting to slow down.

I would strongly recommend changing the O2 sensor(s)... I had a similar issue for about 3 years and changed almost every sensor, plugs, wires, coil, distro cap, rotor button, all vacuum lines, etc... Mine was bank one.. first one after the header
