94 Z28 died again. Ideas?

The latest problem I am having is a weird one. Car was running fine after driving about 15 minutes. Parked car and came back about 10 minutes later. Car started, went about a block, the gas gauge went all the way past full (actually into the temperature gauge), the car started bucking wildly and then died.
On attempted restart, it would barely run while constantly pumping the gas.
Went back 2 hours later, started right up and drove it home.
Parts replaced since I bought it in January: Fuel pump, opti-spark, water pump, 90% vacuum lines, TPS, IAC and ICM.
Any ideas would be appreciated.

Thanks. Finally tracked it down. The ground wire on the connector inside the gas tank at the top of the sender unit had an intermittent connection.
Thanks for your help.
