sounds like it is staving for gas after a minute or so and couple minutes later runs normal

 

could be a number of things, hve you done any preliminary investigtion. is the check engine light on? so many things it could be but coolant temp sensor stands out, it it's telling the ECM it's at operating temp when it's actually cold it would be sending considerably less fuel hence starving it. when was last tune up? fuel filter? have you used a different brand of gas?

 

Need some basic info before anyone can help like year, model, engine. But looking at at what you have listed you have a 96 GC if this is the Jeep you need help with you should post in the GC section. This section is for the XJ.
