Red face what is wrong if my suburban is shuting itself off

what is wrong if my suburban is shutting itself off when im driving. the sterring wheel locks up and i have to turn the key off and then back on to go again.. then eventually it wouldnt even start back . i have to mash the gas to get it to start back so i could get home.. i cleaned the throttle and put new fuel filter on and it seems like its doing better i actually made it home with out it turning off and it was so bad i couldnt go a mile with out it turning off 3 times. is there something else i should try?

Also, some ignition problems can masquerade as fuel problems, i.e. seems like it isn't getting gas. Recently had that problem with my wrecker (350 Chevy engine). Turned out to be the coil, but other suspects would be the rotor and/or ignition module. Rotor is the cheapest part, followed by the coil, with the ignition module usual;ly being the priciest.
