They need to figure out what you're losing. Is it spark or fuel?
I was having the same problem with my 2002 durango thought it was the spark plugs to my surprise when i saw it wasn't my spark plugs and it was due to a dirty throttle body. there was so much gunk in it was suffocating the engine so went out and bought a bottle of throttle body cleaner and a tooth brush and cleaned it really good now it is running awsome! and im even getting better gas mileage to due to better air and fuel mixture :)

It may be your brainbox (or power control module). Thats what was wrong with my 2002. It would cut off for no reason. It's expensive though.
