I'm typing on my phone and this is long so I appologize. Today pulling my 18 ft. Travel trailer in Nebraska on our way home to philly from Denver. The car ran fine most of the time about 2500 miles ago it started losing power for a split second usually during acceleration. It was rare but coming into dodge city is started doing it a lot and I had to slow to 60 and it cut out a lot. The dealer in dodge city did a 200 diagnostic and found no codes accept an old fuel pump code, so they replaced the fuel pump and relay for 1000 more. If made it to Santa Fe but once there it happened once, so I changed plugs then I drove 600 trouble free miles then it started again going up a hill from crested butte to Denver. I decided to head straight home and take it to my mechanic at home. It was doing it a lot leaving Denver but I had gone almost 150 miles without issue then going 80 mph the engine cut out and didn't come back I coasted to a stop put it in park turned the key and nothing no click the engine doesn't turn over. The battery is good. Everything electric seems to work but turning the key has no effect.
