Check for a clogged catalytic conveter or weak fuel pump. Remove the O2 sensor so exhaust can flow out hole and test drive it. If it's better replace the cat or look for kinked or dented section of the exhaust. If it didn't help, have the fuel pressure tested as well as the ignition advance and timing chain.

TRY TO TIGHTEN THE PCM CONNECTORS UNDER THE HOOD ON THE PASSENGER SIDE FIREWALL. COULD BE A BAD CONNECTION. THERE ARE THREE LARGE WIRE CONNECTORS GOING INTO THE COMPUTER HELD IN PLACE BY THREE BOLTS. YOU'LL NEED A 10 MM. SOCKET AND A RATCHET.HOPE THIS HELPS. GOOD LUCK

if there are no codes you might have a dirty fuel filter or water in the gas, check all of your wiring too.

Most common cause of power loss is a stopped up catalytic converter. If you are saying it shuts off while driving, most common problem is the crankshaft sensor. IF you haven't changed the plugs or wires in the last 30K, it is definetly due for plugs wires, and probably cap and rotor button also.

a bad cam sensor will cause vehicle to shut off while driving, and cause a hard time starting. but this usually sets a trouble code p0340. scan vehicle to see if any codes come up. after it is fixed, erase codes with a obd2 scanner. if you do not have one, you can go to any auto parts store and they will erase codes for free.
