Thanks, further information. When we rebuilt the engine this winter we put in a new tank, sending unit, fuel pump, etc. It's always had a full tank since then, I don't believe there is any water in the system. The car live in a heated garage.
So that eliminates a lot of fuel related issues as long as you feel confident in the parts you installed . I found out the hard way that new doesn't necessarily mean good. Dave69 brings up a good point as well. If you are losing a ground, specifically to the Ignition module or if you have a broken or loose wire to the coil, the ignition could be losing power when the car is under acceleration and the vibrations may cause contact loss.
I'm not certain of any of this...just clutching at straws!! LOL !!
