740 to stops sometimes 700 1986

I have tried but can't figure out why it stops some times.

I can start it and it will run 20-25 minutes and then stop and won't start. I have check with a timing light and have ignition. I can hear the pump run when turning the key on (I have do not have a fuel pressure gauge so I am not sure of the fuel pressure, when it will not start) but the car will not start. WAIT 10-MINUTES and it starts and runs ~ 20 minutes and stops.

I have checked a few things; I did re-glue the heat sink (with the correct electronic's glue) another air mass sensor and I forget what else.

Someone said that I will need to install another ground wire to the electron control module but I would like someone else to tell me their experience.

I know that this must be something simple that gets hot--stops and then cools off.

In the meantime it waits in the garage.
