Guerrero returned in 1998. The team's sponsorship from Pennzoil had left for the new Panther Racing founded by former Pagan crew chief John Barnes. Despite a lack of funding Guerrero ran respectably in the first four races of the season. That lack of funds brought Stevie Reeves on board for the fifth race of the season. Reeves finished 10th, but prize money did not allow for the team to continue and it ceased operations for the rest of the season. The team returned in 1999 with Jeff Ward and minor sponsorship beginning with the Indy 500. Ward finished in Pagan Racing's best finish of second place. However, Ward had few other good finishes that season and finished 11th in points. Funding uncertainties returned at season's end and the team was again without sponsorship. It fielded an entry for Richie Hearn in the 2000 Indianapolis 500 where Hearn was knocked out by an electrical problem. The race was the team's last as rising costs finally put an end to the small team from Texas.
