I just spent 4 days of a 14 day vacation hunting the same issue. After several "TESTS", I decided that the computer had issues. Not so!! I found that the out put voltage to my fuel pump relays was less than 11.25 volts (my battery had a full charge and is nearly new). Having found this I started checking for loose connections, broken wires etc.etc.etc. What I found was that the ground wire that comes directly off the battery has a "quick connect" near the battery. It took some efforf to disconnect this connection, when I did I found severe corrision. I removed the bad connector, did a butt splice and applied heat shrink. Bingo, the issue disapeared. I guess that the computer will not work properly with less than a perfrct ground.
