Need help with 88 jimmy

[vettekilr]

The last week or two the truck has been losing power,at first i was thinking tranny,now im thinking torque converter.When I punch it the rpm's only go to 2800???The engine runs fine,the truck is a complete dog,u guys have any ideas THANX

Plugged cat converter? (very common)
Fuel filter plugged? (kinda common on neglected/high mile trucks)
Fuel pump dieing? (kinda common)
E brake stuck on? (stupid question I know, but Ive seen worse)

Need more info like: milage, fairly recent maint done, any SES light, other drivability symptoms besides it wont rev past 2800RPM, etc.
