| I've experienced a very serious/dangerous problem on 9/5/03, 11/1/03, 11/2/03 & 4/18/04: the engine has completely shut down while i was driving my suv. this has happened while i've been driving on hwy, on bridges/ tunnels (withh no shoulders), & when i've stopped the suv @ traffic lights & stop signs. the common denominators for the engine shutting down seem to be: (1)long distance travel-on all 4 occasions i had been driving the vehicle on the hwy for 100 or more miles @ speeds of 60-70 mph before the engine would begin shutting down (2)weather- on all 4 occasions, the temperature was 75-85 degrees when the engine would begin shutting down what typically happens when the engine shuts down: while actively depressing the accelerator pedal, i would suddenly notice that i was no longer getting any acceleration power i would then begin to pump the accelerator pedal to no avail all the lights on the dashboard illuminated, signaling the engine shut down when possible, i would pull over to the shoulder, & crank the ignition 1-3 times before the engine would start again. on the days that i experienced the problem, the engine would contin. to shut down every 1-5 miles, (more frequently in traffic). the engine would contin. to shut down until i could reach a safe destination & allow the suv to rest for several hrs. in total, the engine shut down 10-18 times on each of the 4 days that i had the problem. the engine would shut down mostly while i was actively accelerating, but also happened frequently when i would brake while in traffic, & when i was stopped @ a traffic light/stop sign; occasionally, there were times when i lost all acceleration power while actively driving the vehicle, but the engine didn't actually shutdown. after 10-20 sec. of having no acceleration power, i could suddenly accelerate again. when the engine shut down, there were no signs of overheating & i had at least 1/3 tank of gas. | |||
