Truck Starts And Drives Fine But Once It Warms Up It Dies And Wont Start For A Few Hours..

I have a 2003 Dodge Ram 1500 3.7 V6

The mornings are my favorite part of the day. This is because it’s when I know my truck won’t be giving me problems. That is until the truck starts to warm up. I have no problem when the truck starts for the first time, but when I drive it for a little while the RPM’s will start to fall and it’ll feel like its chugging when I’m driving on the highway. If I come to a stop after it started chugging it will most likely die. It always starts right back up if I turn it on immediately. I have a lot of errands to run during the day, so if the truck gives me problems and I park it I have to wait a few hours until it will start again. I should mention that when it wont start it is cranking but thats it..

My error codes are telling me I have a bad crankshaft position sensor, and I’m also having an Ignition Misfire, but it’s not specific where.

I’ve already replaced all of the spark plugs, Crankshaft Position Sensor, two of the distributor coils, checked all of the fuses, and the fuel pump, fuel pressure, and cleaned the throttle body.

I’d love to take it to a mechanic and have the shop solve my problems but I can’t afford the repair charges at this point in time.

I had a friend come over the other day and look at my truck. We took out one of the distributor coils and one of the brand new spark plugs and when we cranked the engine the was no spark coming from the plug..
