Regina car? Either way, check/change/solder the fuel pump relay. give it a few taps, might get you going again. last year my 93 (Regina) did exactly what yours does. Driving fine, then no power, it was the relay. I resoldered and was back on the road. Next would be the crank position sender, these can go out and give intermittent operation. As can the radio suppression relay (RSR); however, in my experience the RSR is less hassle than the main relay (assuming it and or wires are not corroded). Of course, this all assumes you have good fuel pressure. Good luck.
