98 Jeep Grand Cherokee Laredo Starting/Stumbling/Stalling Problems

Okay, so. This Jeep has been nothing but trouble since I bought it and frankly if I was dishonest enough to sell a broken car I would!

Used to, it would just stall while driving. It would drive for about 10-12 minutes, then stumble until it stalled. Recently though it will start, idle high and rough, then shut back off within a few seconds. I have cleaned the Throttle Body and replaced the TPS. I'm about to clean it with seafoam, but I'm also very wary of just throwing money at it. There is no CEL also. Any help/advice would be appreciated.
Thanks,
Nathan

Welcome to the garage.
Which engine does it have?
Did you check the fuel pressure at the rail?

Also, where are you driving this?
Some older Jeep engines that will run just fine on fuel purchased outside the Los Angeles metro area won't even idle properly or run worth a darn at lower engine speeds on "LA foo foo gas"

It has a 6cyl 4.0 engine, and no. I completely forgot about checking the pressure to be honest! And I live around the Memphis area, so I'm a few ways away from LA lol.
