On yo9ur 91 740 turbo there are two radio suppression relays- one mounted on each shock tower. Remove them and remove the silicon seal. Remove the case on each one and resolder the circuit boards. The solder has a tendency to crack around some of the connections- visible with a magnifying glass. Just spend a few minutes resoldering them and then reseal the case with some silicone caulk. While you are at it remove the fuel pump relay from the tray under the ashtray and give it the same treatment (without the silicone). If I remember correctly it is on the left in the second row. Bad connections in any one of these relays can result in the behavior your car is displaying.
