My '90 Miata, which I have owned for one month has 91,500 miles on it. It runs great except when it's warmed up and I am coming to a stop, the engine shuts off. I can restart it and it starts and runs fine, tach steady at about 750 rpm, then I take off and when coming to the next stop, it will shut off again.
I'm thinking maybe a new gas filter. Anyone had this problem or knows how to fix it. I've looked at the Miata Enthusiast's Manual and haven't found the answer. Thanks, Wileyman
While I have a Miata, I have not had that, or ANY, problem with it.
I DID, however, just have and fix that exact same problem with my Chevy chassis RV. About 2 years ago, I had a very similar problem with my GMC Suburban.
Both vehicles suffered from bad, in-the-tank, electric fuel pumps. The Chevy chassis RV only had the problem when the gas tank was less than 1/2 full..
After replacing the pumps and ALL in-line fuel filters, I have had no problems.
Please let us know what it is.

At idle-- Fuel usage is low, and the voltage to the fuel pump may also be low.
A failing pump may quit at a lower than nomal input voltage. (Usually a sign of a battery or alternator problem.)
I'd jumper the tens pin, and see what happens. Since this is a 90, a lot of things are suspect, based upon age and miles.
I think a good check over the vacuum lines might be a good idea, if they're looking old and dry with some cracking maybe you should replace them. Maybe a long shot but it's a cheap one.

I have a 1990 Miata that I've owned for eight years and that has started to exhibit the same problem, along with occasional difficulty changing gears. It's in the shop at the moment, and it's looking as if the problem was a leaking clutch slave cylinder. Apparently, the leak resulted in the clutch not being fully disengaged when I pushed down the clutch pedal. The mechanic is going to install a new component, to see if that takes care of the problem. However, not having the clutch completely disengaged would explain why the engine would occasionally stall when I was coming to a stop, and why the gears would grind when I was changing them.
