Damn Stalling

[vstar650ca]

Hi all Have a 94 ranger 2.3 auto.Replaced computer,IAC,plugs&wires,ignition switch,fuel pump and relays,coils,alternator etc.In fact the only items not replaced are the speed sensor,tps and coolant temp sensor.Driving down the road at any speed the truck just dies and only restarts when you turn the key off and on again.The truck starts and idles perfectly first thing in the morning.You guys got any ideas Thanks

How about the Inertia Switch?

They can fry to the point where they are intermittent and will cause stalling sporadically...but especially if you hit a small bump...you may not even notice the bump so much...but it does...

By pass the inertia switch with a jumper wire, if you still have the problem start looking at the ignition switch electical part, try wiggling the key part with the engine running also try hitting the wheel with the palm of your hand to create vibrations in the switch, and last go thru and do a wiggle test on the engine harness and body harness with engine running, be care full around any running truck or car and be sure tha parking brake is set and at least 2 wheels blocked
