Car was running fine left work to go home. Stopped at a stop light and took off car bucked and acted like you turned the key off and then back on. As long as I kept light pressure on throttle drove home fine. If you gave it to much gas it would start doing the bucking thing again. Pulled in driveway now car will start up and run about 2 seconds then die. Has 3.3L engine. What are the steps to fix it. Seems like fuel but on the road it seemed electrical.

I would start by checking the fuel pressure. It may have a failed fuel pump. You will need to go to a parts store and get or rent the tester to see what the pressure is.
