This just started yesterday and I'm not quite sure where to begin. When i was driving from a complete stop i put it in 1st gear and it was fine but as the RPMs got higher it seemed as if it was struggling to keep the power so i switched to 2nd and the same thing happened. Fine at first but struggled to hold the power. ANY ideas please help. I replaced the CPS a year ago. spark plugs are good. I'm not quite sure what else to do

Please help. I've got an 89 Jeep Comanche that was driving fine yesterday and today when i went to start it; it would start and stay on if i kept the key in the start position, once I let go it would stall out. hope someone can help
