Just started. no power when taking off and on hills. ant suggestions ran fine that morning. went to leave at lunch time an it falls on it face when trying to accelerate. weak accelaration even on flat and down hill surfaces

Hi Mike:
Since you've solved the gas problem, it looks like you're just dealing with a bad battery.
Try getting a jump with boosters to get it home.
Then check the battery......... fluid level....... Will it take a charge...... Will it hold a charge.
are the terminals and connections all good?
All the fun stuff.
Enjoy

Here's a link to your misfire. P0301 Dodge Cylinder Misfire Fault Detected ,check this video out. Why Do Engines Misfire P0301 Code

Starter solenoid or just a starter bad, sometimes this comes out of nowhere but usually you can hear it start cranking slow shortly before failure.

Check the vacuum line on the fuel pressure regulator for any sign of gas being sucked into the line. A failed regulator will let extra gas get into the engine. If it's okay, have the fuel pressure checked. That's sure a lot of gas, way too much for the engine. Good luck.

Low power lean conditions cracked air intake tube GM Testing by a qualified repair person with proper diagnostic tools is the way to a proper fix , not someone guessing !

Run a scan tool to determine problem, if nothing found take the car to the nearest acura service center to check for any recall onthe car.

This may be a dumb suggestion, but have you tried changing out the battery? I had a similar problem and changed my solenoid, cleaned all grounds and wiring connections and after all that it ended up that a cell was shorting out in the battery. Something to check out anyways. Good luck and hope this helps.

Have you checked the heater plug relay?

tell her to not use the radio at lunch ..she is draining the battery...replace battery..recommend gel type with deep cycle rating highest you will afford and if she must ..run engine at lunch time to charge system

it sounds like your fuel lines aren't maintaining pressure and the angle is allowing too much fuel to drain out of the lines. i have the same issue with and older f350 diesel if i let it sit a while and it doesn't get started.
