What you are describing is a classic low fuel pressure symptoms. After 20+ years of service either fuel pump or the hose that connects pump to to the tank feed through are getting tired. TBI system is designed to operate at about 13 PSI, but will still function down to about 4-6 PSI. In other words.

Check your fuel pressure at TB
Check fuel filter
