94' GT 2.2 , intermittent stalling Options

[popadoc]

I have a 94 GT 2.2 that stalls intermittently. Sometimes I can drive 1 mile before it stalls and then it may go over 100 miles before it happens again, but it has gotten more frequent.

I am getting no codes, the CEL does not stay on, only getting a quick flash just as the engine stumbles and stalls. It will restart right after stalling most of the time, then other times I will have to let it sit for a couple of minutes before it will restart.

Its gotten to the point where I don't trust it enough to leave the driveway. Yesterday it would run for two or three minutes then cutoff. I repeated this 5 or 6 times, it did the same each time. I did notice that there is a hard miss a second or two
before it stalls out.

I have replaced the fuel pump with no change.

I know there are a lot possible things that it could be and I am not looking of a diagnosis , just wondering if someone else has had an issue like this that could help me narrow down the possibilities a little.

Thanks for any help you can give

Was able to get code 13 using diagnostic port under the hood. ''engine speed sensor''

Not sure where to go from here.
