My car wants to stall at different times, it will run well then all of sudden it wants to stall. Even on the highway it will lose engine power. Even if you press the excelator it still acts like ther
First, tell your friend that if a fuel filter is clogged up enough to cause stalling, it will also cause the engine to not run at all. Yes, fuel pumps can work intermittently when they are going out, but it is rare.
You didn't bother to mention what YEAR, MODEL, or ENGINE SIZE you are talking about, so I cannot check for specific information (like Technical Service Bulletins) for your vehicle. The only thing I know about your vehicle at this point is that it is a Jeep. (This is really need-to-know information - especially when you are wanting information on why your engine is not running correctly.
Then, before you start jumping to any conclusions about whether it is being caused by the fuel pump or if it is being caused by a clogged up fuel filter, it would be wise to first PROVE that it is even being caused by the fuel system at all, and not the ignition system. That is the first step...ISOLATE THE SYSTEM. Only AFTER that has been done, should you worry about which PART of that system is causing the problem. (Just a little Automotive Diagnostics and Repair 101)
With all that said, Jeeps are notorious for bad crankshaft position sensors causing the symptoms you are describing.
