Yes you mass air flow sensor could be the issue. But could be a number of other things too. First I would inspect plug wires. Might have one that is bad and every once in a while it shorts out on metal. (Or hot manifold). Also check battery connections. Could be losing the negative connection due to loose/corroded terminal or loose/dirty on the frame or motor.

Dandyoun is correct it could be the mass air flow sensor. But I like to start with the cheaper sensors first. The mass air flow is $350. Try replacing your MAP sensor and your air temp sensor first. For about $50 you can replace both of those first to see if that will fix the problem. http://www.partsgeek.com/catalog/1994/chevrolet/lumina/fuel_injection/ air_temperature_sensor.html
