88 190e fuel pump/relay test

[mboone]

My 88 190e has been in the shop having the transmission rebuilt. When they take it for a test drive it runs for about 10 minutes and dies. After sitting it restarts and the same problem occurs. What is the test for the fuel pump and fuel relay? The filter is fairly new. Any other suggestions would be great. I am trying to avoid another tow from the transmission shop to another shop to another.

Wonering if it's a fuel tank venting problem. Maybe give it a try with the cap off?
