i started it up and let it idle to warm up the engine then drove it down the road about a quarter of a mile down the road engine starts to stumble and act like it is going to shut down so i come back and it dies on me in the drive way b4 this it idle fine and now it wont even start it keeps flooding it self after i drive it and it shuts its self off then if u wait a day it starts up fine and idles fine but when it gets warm it shuts off and back fires through the intake when driving it what could be the cause of this i replace the injector and fuel pump and spark plugs and control module and cap and rotor and wires and coil and battery and belt and fuel filter and map sensor and tps sensor haven't changed the egr valve ive even changed the oil pressure switch and fuel sending unit don't know what it could be

Mine quit running. was doing same thing. Replaced nut kit. That was not the problem. replaced the fuel pump. That was not the problem. The injector (inside the ram tunnel) had broken BOTH the mounting holes and it had BACKED OUT, was flooding manifold. (the screws that held it in were still screwed down tight. Did not buy a new injector instead I got some fine wire and wired that thing down tight so it would never do that gain. That was a year ago. Jimmy runs great. See to it that your fuel pump is giving you good pressure.
