I have 2011 ram 1500 5.7 liter hemi big horn with 177,000 miles the problem first started when I left truck fir about maybe 45 minutes to an hour when left idling fir sbout 15 to 20 minutes then I started driving when right before the highway at a stop light slightly uphill it stalled on me so I used my obd2 reader ad it said mass air flow sensor so changed it because I had just bought the sensor earlier but it still didn’t start so I had it towed to the mechanics he said it was the solenoid cylinder so I changed it still owe him money for that job since it was expensive for me but I got the truck back and not drove like rough on stop light it would hesitate to accelerate and I noticed the the rpm needle would be low unless I tapped the gas then it would go to normal but still hesitate now it dued on me again so I towed it to the mechanic again and told him that before it died the check engine light came on the. Went away before it died I picked up truck couple hours later he said everything looked good told me to drive it again so I did still ram like crap then check engine light came back on when I was parked at home getting ready to go to work I had it warming up for about 20 minutes when first the check engine light comes on and it stalls and won’t turn on it gave me code p0339so I changed both camshaft and crankshaft it still doesn’t turn on I’ve done everything to try and solve the problem from new spark plugs to fuel injectors and intake manifold have all been changed new sensors for the thermostat sensor even new radiator cap I’m lost and can’t afford new car
