Power shutdown car starts fine but, once driven down the road a ways it just suddenly shuts down all power. Fuel filter was changed a few months back!!! Also transmission light stays on all time. Engine was just replaced within the past month!!

Sounds like you got some bad gas. May need to replace the fuel filter

There could be a problem with the security system or the main computer could have a burnt spot or a crack in the board. Had an issue a few years back with a Dodge Dakota will run fine when a computer got hot it would shut down. I would take it and have it put on a scanner to see if there is any codes then go from there

Low oil will not cause the issue you are describing..

ck electric side of switch start car and wiggle key around if dies replace

replace engine coolant temp sensor

Hi! I suspect a faulty fuel filter. The filter may be clogged with dirt and rust causing the car to stall. Once the dirt and rust subsides, there goes the engine running again and when it blocks the fuel line it dies again. Drain the fuel tank and separate dirt and rust and replace the fuel filter. This will solve the issue. Hope this helps and have a good one!

fuel pump and or filter is my first guess

have you changed fuel filter or pump?

Replace the Fuel Pump. I had the same problem and i did everything you did to find out that it was the fuel pump. I removed the tank and repaced the fuel pump and bingo! No more problems the car runs like new

If this happens every time you start your truck and it shuts off the same each time, you just might have a dirty fuel filter only allowing so much gas pass through until it clogs once again. I once had a chevy van, when I would drive it, would go a few miles and engine would shut down.   I would wait 10 or 15 minutes, it would start up and allow me to drive a few more miles then shut down again.  I changed the fuel filter, It was fine after that.
