2009 Jeep Patriot fuel system problems

Bought car in nov with clean carfax - 5months later it seemed to have a fuel injection problem. On way to the dealer, car did not stall, but speed dropped to 30-35 MPH on the highway (engine light came on) had to drive in breakdown lane with hazard lights flashing, and on exit ramp shoulder . Trying to pull out into the driving lane on ramp- speed dropped to 5-10MPH. - no acceleration.. Car was hit by another vehicle just behind the front left wheel - the car was totaled...cause still unknown.

12/12/19 tried to get on I-295 all lights on dash came on including malfunction indicator, esp bas, and others all came on when no lights were on before. Lost power to jeep on 295 could not go any fast then 25 MPH and then stalled; almost rear ended. Could restart jeep, all dash lights still on, no power past 25 MPH and made it off an off ramp where stalled again. Towed jeep to mechanic where they replaced PCM, intake manifold, and o2 censor.
