My Jeep lives... no thanks to Chrysler engineers. I have had an issue with my Jeep randomly stalling for about 3 years. I researched the internet, Jeep clubs, and spoke with several mechanics. Needless to say everyone had a different solution. It ended up being the wire going from the Alternator to the battery and fuse box. Something none of the experts even considered.
Those of you who know about wiring... Chrysler engineers used 8-AWG wiring from the alternator and 6-AWG for the starter and the negative/ground. I discovered an issue with the wiring after I had played the role of a typical mechanic; testing and swapping out all of the usual culprits. I connected my 1/0-AWG jumper cables between my Jeep and my car. When connected, the Jeep ran OK, it stalled every know and then, but would start back up after a few seconds. If I disconnected the cables, the Jeep would die with in 5 minute... every time.
So... I tested the alternator. It was operating perfectly. So, why was my battery going dead? And, why was my Jeep dying? I removed the flexible plastic cover from the wires coming off the battery and the alternator to discover, (a) they were unusually small in diameter and (b) they had several burn marks along the wire run.
I have enough of a background with electronics to know that the skinny little wires were overheating and causing a drain on my electrical system. Think of running a compressor with a cheap extension cord... you get the picture.
I replaced all of the cables with 2-AWG, 300 amp, 680 strand welding cable. A little overkill, YES. It works beautifully. Love my Jeep. Total cost was $90 including tools.

check to see if there is a hidden fuel filter in a black plastic housing in the frame rail between the fuel tank and the pressure fuel pump. It has 4 fuel line ports. Use a band type (oil filter) wrench being careful not to break the plastic bowl unscrewing it. Its tight to unscrew, I had to slightly bend my brake-line out of the way. The filter inside is 1 1/2" tall by 2 3/4" wide.

after finding this hidden filter, My truck has been running like a top, U would think, The big filter would do the first main filtering, and the small filter would be the after filter, but not on this ford, the housing doesn't like it unscrews having a filter inside, Its been missed over the 20 plus years, I'm sure this was why the prior owner sold it giving up trying to solve this problem of stalling out starting back after setting awhile purring like a kitten for the next few miles then repeating over,

Victor, I may be wrong, but that sounds like a vacuum leak from the brake booster. It's most probably a cracked hose.

I have a 99 Dodge Ram that my engine won't stay revved up if I mashing the gas pedal to the floor it surges what could be causing it to lose power and then rev back up repeatedly. It's like a cell phone on vibrate. Whole story, it had just rained here and I stopped to fill my tank at the station,. Immediately 1 block away I started having issues, loss of power, popping and cackling, I assumed bad gas. I put gas treatment in and sea foam revving it up and down trying to burn the water out it died a couple times kept revving it up and eventually it start working its way out it's still backfired and still really didn't have much power so I push the pedal to the floor and got it running at high RPMs and then that's when I noticed that it surges.
