I have a 99 Jeep Grand Cherokee with about 183,000 miles. Over the last couple of days it has developed a problem where when accelerating it will lose all engine power for about 5 seconds (rpms drop and and then regain power with a short burst of acceleration). It feels like it's running out of gas. I already replaced the air filter and fuel filter, those needed to be replaced anyway, but it didn't help.
Other than the power loss, it in general feels sluggish, like I'm constantly towing something. No check engine light. Any suggestions of things to check or other symptoms that I could look for that would help diagnose it?
