The car will not start

My problem started when I drove to a gas station to get something to drink. I left from home and drove about two miles to the gas station. When I got back in my car it started fine but I put it in reverse and it stalled. Started right back up and got drove to stop sign and as I pressed the gas to go and it felt like it had hiccups until about second gear that it ran fine till I parked it. Turned it off and waited thirty seconds and started the car right back up. The next day it stalled after it was warm. Only when I put the car in drive or reverse. Than the hiccups in second going to third. Not a bucking. So I replaced the fuel pump. Fixed the problem for a day or two. Then back to the previous conditions. So I changed air filter, checked mass air flow sensor and it was good. Changed EGR value, crankshaft sensor, camshaft sensor, PVC valve. Same problem continued. Charged spark plugs and wires. Started it up to warm it up and it stalled after four minutes or so. Would not start up after that. Changed ignition switch and key lock cylinder Either Née keys. Did the ten minute relearning process, security light went off. Tried to restart and still nothing. Will crank but not start. Also checked the coil packs and they are good. Need help! Where to go from here? No codes pop up. On four different scanners.
