Cars stalls when you let off the gas idles great only dies while driving

Car starts and runs great at operating temperature. When driving down the road when you let off the gas it dies 80% of the time. After it is in park it starts right back up. There are no check light on on the dash replaced crank shaft sensor, fuel pump still dies. Check engine light is on, the code said lean fuel trim. I replaced MAF sensor still dies but now no check light. I check all vacuum hose spray water around all hoses and intake and throttle body does not stall when driving cold just when warmed up. Please help at wits end.
