Update, my problem continues.
I pulled the fuel injectors, cleaned and flow tested them. Both produce a good mist pattern with no streams and have equal flow. Fuel pressure was checked and I'm getting 70 psi at the injectors. Fuel was flushed and everything verified to be clean. Finally, I replaced the spark plugs for good measure. After doing all this the Morgan started right up and ran fine for about 30 min before suddenly shutting down again. When I attempted to restart I did not hear the fuel pump pressurize, although I could hear some percolating sounds I'd not noticed before. I'm guessing that may be the fuel return??? There are no dash warnings. If I let the Morgan sit for a while and restart, I hear the fuel pump pressurize and it starts right up and will run for a while before shutting down again... rinse and repeat.
Any suggestions are welcome.
Thanks,
