I have a 1993 Ford Explorer with a 4.0 L that started stalling while driving about six month ago. It shuts off like someone turned the key. Originally you could push in the clutch and immediately restart it without a problem. The occurrence is very random and there is never anything common between occurrences. It used to happen only one time during a day until about two weeks ago when it happened twice within about 10 minutes. It took about 10 minutes each time before it would restart. Both those times, even though it died like the key was turned off, it acted like it was out of gas when I was trying to restart it and then all of the sudden it would start like normal. The problem seemed to start about the time the vehicle was run extremely low on gas. Since then the following has been done: fuel filter replaced, tune-up performed (plugs and wires), fuel pump and EEC relays replaced, MAF sensor cleaned and the IAC valve inspected. The service shop where it is taken says there is never an error code in the system when I bring it in. The vehicle is currently unsafe to drive with this condition. Any suggestions as to cause and solution are greatly appreciated.
Thanks,
Rich
