One of the accelerator position sensors may be bad putting it into limp home mode . Have it scanned for codes and post them here .

When you say it loses power, do you mean electrical power or engine power ?
You would need to look at the fuse boxes for a loss of electrical power, and use a scanner or code reader to check the computer for trouble codes for a loss of engine power.

if there is no spark check your positive feed and all conections on the starter motor also check earths round engine bay

I have a similar problem - every once in a while all of my dash lights flash on like the car is trying to conk out/stall (I have a 2006 Jeep Grand Cherokee) - the car has no loss of power and runs fine, just all of the dashboard lights and warnings come on like its going to stall. Happens on dry days, wet days, cold days, warm days - at least 3 times a month. trouble is, because its intermittent no one can find the problem.

Does it die coming to a stop or die when driving. Will it restart if holding down on gas pedal a little? May be carbon on throttle body. Bad crank sensor will cause this also. Doesnt always set a code. Loss of fuel pressure will cause this with no code.

It can possibly be the crank position sensor mounted on the top of the bell housing on the passenger side of the vehicle causing the problem. I have replaced a few of these for the same reason.

not camshaft sensor get transmission oil checked

could be engine mounts have to replace mine engine almost jumps outta the compartment

This is caused by by a bad ignition switch. According to the dealer the ignition switch contains an antenna that many of the sensors use to communicate with the vehicle, as well as the key fob. When the switch starts going bad the vehicle computer losses communication with these sensors and starts producing codes which include the 4wd and the electronic brakes. My fiance has had the same issues with her Grand Cherokee as well as the key fob not working, the remote start not working, the service engine light comes on, the door chime will sound when the key is NOT in the ignition and the lights are NOT on, as well as numerous codes usually relating to loss of communication with one system or another. All of which are fixed once the ignition switch is replaced. Unfortunately, this usually only fixes the problem for a short time (weeks or maybe a few months) before the piece of junk ignition switch fails again and it all starts over.
