Could this be an optispark problem?

Lately I'll be driving on the freeway anywhere from 60 to 70 mph and all of a sudden I'll loose a little power and my rmp gauge will go to 0 rpms. If I tap the throttle pedal the rpms come back to normal and the car acts like nothing happened. A few times the car has turned off on me while on the freeway. Could this be an opti problem, or could it be a fuel problem?

Could be an ignition switch problem.

Are you getting a SES light? If so, scan for codes

The ses doesn't come on. I don't think its a power issue because the lights and everything else keeps running like normal, but I'll check all the connections anyway. It's weird the rpms go to 0 but oil pressure stays the same, battery voltage stays the same, and the car isn't over heating.

Opti's do not make a gauge cluster lose power or connectivity. Still think you may have an ignition switch problem.

I agree w SS RRR
take all your keys off and only have the door and ignition on, no fancy heavy keychain either... =)

It's not the cluster losing power, just the rpm gauge goes down to 0 rpms and the engine loses a little power everything else on the cluster works. The opti itself is a generic opti I got from a place by my house that rebuilds distributors, It's probably a rebuilt Oem opti. I live in Los Angeles so I don't really drive in rain. The car never gives me problems around the neighbor hood, just on the freeway. It almost feels like when I hold the throttle in a certain spot it happens. Could a bad throttle position sensor be causing this?
