I have an 89 mustang 5.0. Weird thing happening. The mustang will start up with no problems. I drive it to work in the morning. It sits for a few hours. Starts up fine when I take it to lunch. Sits 2 more hours I drive home. Starts fine. I then drive home about a 45 minute commute. I stopped on the way home to get a quick drink. Came back out the car started but then quickly died. Try to start again it just pudders then dies. Battery is reading 12.5V, everything is powered. If I let the car sit for 10 minutes it will start back up and run fine. This seems to happen when its hot out. This is the second time this happened. Battery and alternator seem fine. Car is not overheating. Could this be a timing problem or wires getting to hot. The interesting thing is the car runs great until you shut it off then it seems to pudder on the next start. Any ideas would be appreciated.

What fuel pump is in it?

it could be your starter...if it gets too hot car will have trouble starting, you might need to get a heat resistant insulation sheet wrapped around the starter. you might need this

+1 on the warm starter then I'd go the overheated tfi

Sounds like the TFI Module on the distributor is going bad.

Thanks for the ideas. The starter will start the car. The car starts but once started you give it gas and the car just doesn't seem to get the amount of fuel it should and dies. I can here the fuel pump turn on. The starter seems to being doing its job. What tests could I perform?

Not sure I bought the car about 6 months ago. I will have to drop the tank and pull this to find out. Just don't want to have to do this if not necessary. I guess I might have to in order to find my problem. Any more ideas or input is appreciated. Thanks again everyone.

If it was the TFI module wound'nt I have problems after the car is running as well? The car runs great until you turn it off after a short commute and then try to start it.

Is the battery in the stock location? Hot start problem is common when the ground isn't done right when the battery is relocated to the rear, but if not check your battery cables.

I had a car miss from a tfi. I always thought that they either worked or didn't. It's nice if you can swap one just to test it out.

Had the same problem in my vert every time it got hot it would sputter out after I just turned it off and tried turning the car back on but let it cool all the way down and it would start after a while it gets worse

Thanks for all the replies. I am going to replace the TFI mod. I will report back once done. Thanks again for the help.
